Pregnancy test - instructions for use. Preparing for the test. Inkjet pregnancy test Evitest

1) carefully open the package with the test and remove the test strip from it;

2) collect urine in a clean container, preferably the first morning;

3) holding the test strip by the colored end, vertically immerse it in a container with freshly collected urine up to the mark ¦

Do not dip the test strip deeper than this mark.

Test strip - Instructions in pictures

4) after this time, remove the test strip from the liquid and place it on a horizontal dry surface;

5) after 3-5 minutes (but no later than 10 minutes), evaluate the result. During this time, a control strip must necessarily appear, and in the presence of pregnancy, a second, test, strip will appear.

The appearance of even a weak second strip during the first 3-5 minutes is considered a sign of early pregnancy.

Change in result after 10 minutes - do not take into account even if the second strip disappears or vice versa appears.

Instructions for using the test cassette

1) remove the test cassette and pipette from the individual package;

2) collect urine in a container, which is usually included in the kit;

3) draw liquid (collected urine) into the pipette from the container;

4) drop 4 drops of urine from the pipette into the oval window of the test cassette;

5) put the test cassette on a horizontal surface;

6) after 3-5 minutes, the result will appear in the second (larger) window.

The result remains reliable only for the first 10 minutes.

Guide to Using the Inkjet Pregnancy Test

1) remove the test module from the package;

2) remove the protective cap from the cassette test;

3) substitute the open end of the test under the running stream of urine, trying to keep the test slightly vertical, with the receiving part of the test down;

Also, if it is more convenient for you, then instead of step 3, you can collect the urine in a clean, dry container and vertically lower the absorbent part into the urine for 15-20 seconds.

4) put back the protective cap;

5) put the test on a horizontal surface;

6) after 3-5 minutes (but not later than 10 minutes), looking at the window, evaluate the result. Depending on the firm of the test, either a strip (one or two), or a “+” or “-” sign will appear in the window.

If not a single line appears in the window, this means that the test was performed incorrectly or not enough urine got on the absorbent part of the test. Do all the instructions again, only with a new pregnancy test.

Attention! During and after testing, DO NOT turn the device upside down!

Instructions for an electronic pregnancy test

According to the principle of conducting an electronic pregnancy test, it is similar to an inkjet:

1) take it out of the box digital test;

3) for 5 seconds, substitute the open edge of the test under the running stream of urine, holding the test slightly vertically, with the receiving part of the test down, and trying not to wet the rest of the test;

4) as soon as the symbol appears on the screen hourglass, this means that the test was carried out correctly, and the result is being processed;

5) after 3 minutes, the “+” or “-” sign will appear on the display (in some tests “Pregnant” / “Pregnant” or “Not pregnant” / “Not pregnant”), and in case of confirmation of pregnancy, under the “+” sign will be the estimated gestational age is displayed (1-2 weeks, 2-3 weeks, 3+).

Deciphering the result of a digital pregnancy test

After 24 hours, the screen will stop displaying the result. Some manufacturers produce reusable electronic tests for pregnancy with removable cartridges.

Instructions for using the reservoir test system

1) take the test system out of the package;

The test strip built into the reservoir body will only absorb required amount liquid, even if there is more of it in the tank than required.

If the test result is positive, you should contact the women's consultation to get registered.

With a negative result and the absence of menstruation in due date, you need to contact a gynecologist to find out the reasons for the absence of monthly menstrual flow.

How to use a pregnancy test - an affordable way to diagnose

Pregnancy, whether planned or not, needs in diagnostics.

It can be defined in several ways: gynecological examination, blood test for hCG, pregnancy test (for hCG).

Gained widespread popularity pregnancy test, how simple and convenient way diagnosis of conception at home.

How a pregnancy test works

The essence of home testing is to determine chorionic gonadotropin a person (hCG), the presence of which can also be recognized by a blood test, but for this, you need to go to the hospital. With the test, everything is much easier.

HCG hormone It is produced only during pregnancy, and it can be determined by collecting urine. The fact is that the level of this hormone, in the case of conception, begins to rise rapidly throughout the body: approximately twice every few days. Peak it accounted for at 7-12 week of pregnancy, and persists until the postpartum period.

Why can there be a negative pregnancy test? What is the reason: a manufacturing defect or improper operation?

Even with the most careful preparation to pregnancy failures and pathologies are possible. The answer to the question: does the test show an ectopic pregnancy? - In this article.

IN this case, the correct use of a pregnancy test can give high guarantees of an accurate diagnosis possible conception. Although tests can also make mistakes. Causes this can serve:

misuse,
malfunctions in the female body.

Varieties of pregnancy tests

Today, there are many types of test diagnostics of conception:

Strip test (strip)

This most acceptable for the price and comfortable diagnostic test. It is produced in the form of a strip, on which it is marked maximum level immersion in urine and, in fact, the indicator of the hCG hormone itself.

How to use a pregnancy test? In order to test, it is necessary to place the strip in a container of urine for half a minute. Then the test is laid out on the surface and after a few minutes the result is observed. If the test shows two stripes - pregnancy identified, if one - no pregnancy.

tablet test

The instruction for such a pregnancy test is very similar to a strip strip, with the difference that the indicator is placed in a plastic shell. Collected urine drip into a special hole and observe the result. Pregnancy is also defined - along the stripes.

Inkjet test

Its name speaks for itself - there is no need to immerse the indicator in urine. According to the instructions for an inkjet pregnancy test, it is enough place the indicator under the urine stream. These tests are highly sensitive and therefore recommended for early diagnosis pregnancy is their undeniable advantage over the tests described above.

Electronic test

Suitable for both submersible and jet identification of pregnancy. The result becomes known in a few minutes. The electronic window will display the value "+" or "-".

There are tests on which the diagnosis of conception looks like this: “pregnant” - positive result, "not pregnant" - no pregnancy.

On-line pregnancy test

This is another type of testing that is more fiction than the possibility of obtaining any result.

Very often under the guise of such a "test" hides a scam which, in best case, will turn into disappointment, and at worst - a scam with sending SMS and promises of an exact result, in the form of stupid questions or putting fingers to the monitor. "Flight of fancy" scammers have enough. Therefore, never conduct such tests in principle, no matter how "real" they may seem.

How and when to take a pregnancy test?

Before testing, limit reception fatty foods, Better yet, test on an empty stomach.
Shouldn't be tested after sexual contact - this can distort the readings.
It is also recommended to drain the first drops of urine, and collect basic.
Concerning menstrual cycle then a pregnancy test won't make sense until the first day of delay. This is because hCG level can be low enough that the test will give a false result.
Weak second line may indicate normal pregnancy or intrauterine - contact a specialist for clarification.
If the menstruation did not come, and the test showed a negative result - try again this process after a few days.

In addition to the rules for the correct conduct of tests, there are other factors that must be considered for any test:

check packaging with dough- it must be intact
look carefully best before date test,
complete with test there should be a moisture-absorbing capsule and instructions for use, which can also be described on the package itself,
read the instructions carefully- For different tests they may differ
keep in mind that after 10 minutes any test is considered invalid.

These simple recommendations help you determine the "position" of your body. If you have any doubts or “unusual” sensations, and the test indicated a negative result, it is better to contact a specialist.

Pregnancy test instructions

Modern pregnancy tests are very affordable and easy to use. Each of them (depending on the type and manufacturer) may have a different instruction from the others. But most of the same type of tests are applied in the same way. True, each type of test has its own method of application:

Instructions for test strips:

Open the package and take out the test strip.
Collect urine in a clean, dry plastic or glassware and place the test in the urine to the level indicated by the arrows for 5-10 seconds.
Remove the test from the urine and place it on a flat, clean, dry and non-absorbent surface (such as the top rim of a urine collection cup).

Instructions for test cassettes:

Open the package and remove the test cassette with pipette.
Collect the urine in the included cup.
Using a pipette, drop 4 drops into the rounded window of the cassette.
Evaluate the result after 1-5 minutes, but no later than 10 minutes.

Instructions for midstream test (inkjet tests):

Take the test out of the bag.
After removing the cap and holding the test by the handle, place it in the urine stream for 5-10 seconds so that the liquid falls on the absorbent surface indicated by the arrow on the test (alternatively, you can collect the urine in a clean, dry dish and immerse the absorbent surface in the urine for 5-10 seconds). 10 Seconds).
Close the test cap and place on a flat surface.
Evaluate the result after 1-5 minutes, but no later than 10 minutes. Read also Evitest pregnancy test

During the first minute, a wave should appear on the diagnostic field, which will slowly move. If it is not present, it means that not enough urine has got on the absorbent surface or it has not got at all. After the test, one or two dark stripes should appear in the window - this means that the test was carried out correctly, and you can evaluate the test results.

To provide the most high efficiency carrying out the procedure, it is necessary not only to follow the instructions exactly, but also to know when to take a pregnancy test and at what time of day the test should be taken.

The packaging of the test is airtight and should be opened immediately before analysis.
Do not use the kit if the bag is torn or poorly sealed.
Each pack of dough is for single use only.
The kit is for external use only. Do not swallow (do not take by mouth).
Do not use the kit after the expiration date.
Accurately follow the time requirements of the analysis. To do this, it is best to have a watch with a legible dial or an alarm clock on hand.
If it takes some time to wait for the result, place the strip away from heat sources.
Practice shows that on the first days of the delay, the second band appears weakly and after more a long period than what is written on the packaging. But for long periods it manifests itself faster and brighter than the first.
If the kit contains a second test, or if you bought another kit, wait a few days before testing again.
The appearance of even a very weak second strip should be considered as pregnancy.

How to use a pregnancy test - instructions, tips and tricks

Pharmacy counters offer modern girl and women a huge number of varieties of pregnancy tests. What should be remembered when using a pregnancy test? Which type is better to choose, how to use a pregnancy test, when can it be used?

The procedure that allows a girl to confirm or deny the first signs of pregnancy without visiting a gynecologist is called rapid testing. It is held in home environment using special devices - pregnancy tests, which can now be purchased at every pharmacy without presenting a prescription. It is very easy to carry out the procedure, the main thing is to figure out how to use a pregnancy test, when it should be used and which one is better to choose.

How does a pregnancy test work?

After conception and until the end of the first trimester, a unique hormone is intensively produced in the body of a woman - human chorionic gonadotropin, or hCG. Its production and presence in the blood and urine of a woman is a confirmation of pregnancy. It is very easy to identify it with the help of special reagents that must come into contact with the biological fluid under study.

Urine is tested at home. The test is carried out using special devices, which are based on the principle of interaction of the hCG hormone with a special reagent. Such devices resemble strips. They are called diagnostic and are used as litmus paper. Therefore, using a pregnancy test, you should know: if there is hCG in the urine, then the “litmus” express strip will change color, if not, then the color will remain the same.

In the urine, the hormone appears only 10-15 days later (individual indicators of the woman's body) after the actual conception. In the blood, the hormone is determined after 2-3 days. In pharmacies, you can also find express strips of high sensitivity to hCG, however, such tests should be used no earlier than 7 days after the absence of monthly discharge.

Pregnancy test - test strips: pros and cons, instructions

The test strip is the most popular and simplest type of express device. This is the first generation of tests, which has some drawbacks:

The biological fluid must be morning. The highest concentration of hCG is in morning urine, the chances of getting reliable results are much higher.
Urine must be collected in a clean and dry container.
More likely to overexpose / underexpose the reagent in the urine - not reliable result.
The device uses a paper strip. It is rather problematic to impregnate it with a reagent, and therefore the result in 4 out of 10 tests may be erroneous.

But the rules for using a paper pregnancy test are very simple. It is necessary to lower the strip into a container with biological fluid for 15-20 seconds. Then take it out and put it on a flat surface. After a few minutes (in some cases, the reagent may give a result after 2-4 hours), you can evaluate the result:

One color bar- no pregnancy.
Two colored stripes - there is a pregnancy.

Tablet pregnancy test

This is the next generation of express devices. They are much more convenient to use. The test paper strip is hidden in Plastic container tablet or cassette front side which has two small windows. The tablet does not need to be immersed in biological fluid. The usage principle is as follows:

Collect some morning urine in a clean container.
Take the pipette out of the package.
Draw a couple of drops of urine into the pipette.
Apply to the first window in the tablet.
Wait a few minutes.
Look at the second box for the result box.
One band (blue minus) is not pregnant, two (blue plus) are.

The sensitivity of such strips is similar to the previous ones, the only difference is that the “litmus” strip is easier to use. There is no need to worry about what can be overexposed or underexposed.

Inkjet pregnancy test

More modern and sensitive to the hCG hormone strips. They are convenient in that there is no need to collect urine in a container in the morning, and the test can be carried out at a time of the day that is comfortable for the girl. The principle of the procedure is extremely simple: the device from the package must be brought to the stream of urine and wetted. The result will be ready in 2-7 minutes.

Inkjet devices are much better. They contain a fibrous rod, completely permeated with tubules. Through them, the biological fluid enters the reagent, which is located as if in a capsule.

On the shelves of pharmacies, you can also find electronic express devices. Convenient and practical modern tests that have a fairly high cost.

What test to determine pregnancy to choose?

Tests can give false positive results if the girl's body:

there are violations in the work of the ovaries;
a tumor producing hCG hormone has formed.

Therefore, when in doubt, it is better to consult a specialist. A blood test guarantees a reliable result.

Taking medications containing hCG within 14 days before the test
With some diseases of the internal organs
Test expiration date
After childbirth, abortion or miscarriage, it persists for some time elevated level hCG
More than 10 minutes have passed since the test

In any case, the final diagnosis of pregnancy should be carried out by a gynecologist.

2. What are pregnancy tests

Pregnancy tests differ, as mentioned above, in their sensitivity.

The next difference is appearance and method of testing. The test may be classic look — in the form of a test strip(tests of the first generation), they come in various widths, can be enclosed in a plastic case.

Pregnancy tests in a plastic case are with litmus stick, it must be immersed in urine, jet(third generation tests) or cassette(second generation tests) - they need to apply a few drops of urine.

Separately located electronic tests for pregnancy. In the zone for evaluating the result of an electronic test, there is a liquid crystal screen and an inscription-message appears on it indicating whether the woman is pregnant or not.

Additionally, electronic tests can show the approximate duration of pregnancy and / or determine the level of other hormones, such as luteinizing, then in case of a negative result, the test will tell you the most auspicious days for conception in the next cycle. It is possible to transfer the received data to a computer.

Usually, replaceable cartridges are included with electronic pregnancy tests.

The price of test strips depends on the width of the strip itself, sensitivity, design and quality of their packaging (package or cardboard box).

The price of tests in a plastic case depends on the sensitivity of the test, additional comfort options and the brand. Often, the kit sells all the utensils necessary for setting the test (cup, pipette, etc.).

3. How to do a pregnancy test

Let's look at the main nuances of a pregnancy test.

It is recommended to carry out the analysis in the morning, especially on early dates pregnancy
Read the instructions carefully. Different manufacturers may have their own nuances of setting the test.
Open the package. There is always a small bag of silica gel in the kit, it is needed to absorb moisture - silica gel is not involved in the test, it is thrown away. Save the instructions!
Collect the urine in a clean, dry container. For inkjet tests - remove the protective cap and substitute the absorbent part (indicated by the arrow) of the test under the urine stream for 3-5 seconds
For test strips and tests with a litmus stick, dip the test into the urine to the indicated mark for 5 seconds. Inkjet test, can also be dipped in urine. On the cassette test, in the diagnostic area, apply 4 drops of urine
Lay the dough on a horizontal surface and let it lie for 5 minutes. At the fifth minute, evaluate the result. The specified time may vary from manufacturer to manufacturer. Read the instructions carefully!
Rate the test result. Even a weak second line will indicate an expected pregnancy. Compare the test result with the options from the instructions
After 10 minutes the test loses its diagnostic value and should be thrown away.
If a woman has the first signs of pregnancy at a very early date and a negative test result, it is recommended to repeat the test after 3 days

For more clarity, I suggest watching the video.

Conclusion

IN home environment It is possible to determine the onset of pregnancy with a pregnancy test, which can be purchased at a pharmacy. Each test purchased detects pregnancy by the amount of chorionic hormone in the urine.

It is this hormone that rises in the body of a pregnant woman, while in a non-pregnant woman it remains at a level equal to zero. As soon as a woman has suspicions of pregnancy, she can safely go to the pharmacy. By purchasing, you can verify the presence or absence of pregnancy.

The most common and popular pregnancy test is the "test strip". Such a pregnancy test is easy to use, being the cheapest of all the options presented. This test got its name because it looks like paper strip impregnated with a reactive substance.

How to use a pregnancy test

To determine pregnancy, you need to collect morning urine in a small container, dip a strip into it, and then put it on a dry, flat surface. After a couple of minutes, you will be able to determine the result. If only one strip is pronounced on the test, then the result is negative, and there is no pregnancy, in the case when both strips appear, the result is positive.

Pregnancy test. One clear line is visible, the result is negative.

Pregnancy test. You can see two lines, the result is positive. You are pregnant!

The disadvantage of this test is that if it is incorrectly applied, it may not exact result. A tablet pregnancy test is considered more reliable. There are two holes in this test. Urine is placed in the first hole, and after its interaction with the reactive substance in the second hole, a positive or negative result is demonstrated.

The most accurate pregnancy tests

The jet pregnancy test is endowed with the greatest accuracy in determining the result. The cost of this test is significantly higher than the others. The basis of the test is urine, which turns blue when reacting with. It should be understood that it is most rational to use only in certain period time. The production of the hCG hormone begins after a week from the moment of fertilization.

The most reliable results are determined after the first day of menstrual delay. In view of this, from the moment a woman can safely conduct such a test. In addition, there are tests that determine pregnancy from the first day of conception or a week before the expected menstruation.

These tests include inkjet tests. Almost all pregnancy tests show a result with 99% certainty, which is why this method can be used with confidence to determine pregnancy, making sure of its effectiveness on your own example.

If doubts about the effectiveness of the test used are not left alone, the best way out is to visit a doctor who, by touch, will determine the presence of a corpus luteum in the uterus.

In the case when there is a delay in menstruation, then doubts arise in the soul regarding a possible pregnancy. Most reliable way, which can dispel all guesses - a visit to an obstetrician-gynecologist. For more than ten years, the modern generation has already known methods for early quick diagnosis, which are aimed at detecting pregnancy at home.

On the shelves of supermarkets or pharmacies a large number of types of tests that determine pregnancy, which differ in brands, price range and, of course, diagnostic accuracy. However, despite such a rich variety, all tests have general principle actions - they are aimed at detecting the level of human chorionic nadotropin (hCG) in the urine. Accuracy various tests explained only by different reagents. In this article, we will look at existing species tests and principles of their functioning.

Methods for determining pregnancy

For many years, the most common and fast method establishing pregnancy is a pregnancy test. Almost every woman in her life dreams of seeing two stripes, which actually state the onset of pregnancy. There are several types of express tests that confirm the presence of pregnancy.

Instructions for use

It would seem that all diagnostic express systems are not at all difficult to use, but before using them, you should carefully study the instructions. Since, for example, to provide a result, some tests can be substituted under a stream of liquid during urination, while other tests should be held in a container in which urine must first be collected. In many cases, it is desirable to use urine collected in morning time, since during this period it is most concentrated and contains more hormones.

There are two strips on the test, the most basic of which is the “control”. It should show up anyway. If the "control" strip does not acquire color, this indicates that the test is defective. As a rule, the control strip is located at the top of the test.

When the test needs to be immersed in a container where urine is located, be sure to make sure that the test is lowered to the designated level, it is indicated by a line above the arrows. Many tests need to be held in the urine for 20-30 seconds. To ensure accurate results, make sure the strip is free of dirt or moisture before testing. It is also forbidden to touch the reaction part of the test with your hands. You can evaluate the test results after 5 minutes. Most often, the first strip appears immediately, while the second, if pregnancy is present, after a while. The result cannot be considered positive if the second strip appears after 10 minutes.

When buying a test, check its expiration date. False positives and false negative results may be shown if an expired test was used. Please note that the test can show a positive result in normal and ectopic pregnancies. However, using the test, it is impossible to diagnose an ectopic pregnancy.

regular test strip

The strip test is an affordable and simplest diagnostic aimed at determining pregnancy. The strip of this test is coated with labeled antibodies and reagents that react to hCG at diagnostic and control levels. These test strips can detect pregnancy from the first day when your period is missed. To conduct a test, the strip should be dipped for 1-3 minutes in a small portion of morning urine, then it should be placed on a dry surface (preferably flat) and the result should appear, which will appear in 3-5 minutes. The appearance of stripes is the result of the test, where one strip indicates the absence of pregnancy, and two indicate its presence.

Tablet tests

This type of test confirming the presence or absence of pregnancy has the form of a test strip, which is located in an elongated plastic case, it is usually accompanied by a pipette designed to collect urine. The result revealed by this test is 99% reliable, since it has a design that which is aimed at the correct and accurate principle of the test. If, nevertheless, there are doubts about the result, it is advisable to repeat the test again.

tablet test as well as the strip test has the same principle. A special reagent is applied to it. Nevertheless, this species test shows more reliable results than the test strip. The tablet test is recommended to be carried out in the morning, preferably immediately after waking up. It is necessary to collect a small amount of urine in a special container, then draw it with a pipette and drop it into the window located on the test. In case of a positive result, the test will appear within 5-7 minutes.

Inkjet tests

The most modern tests are inkjet tests, which have a more complex design, due to which they are more accurate and convenient. It should be noted that the price category of this test is higher than that of its predecessors. The inkjet test is particularly reliable because even if faint streak, then this indicates the presence of pregnancy. Since this type of test has a high sensitivity, it can be carried out in different times days. However, it is preferable to carry out this test also in the morning, in particular for early pregnancy.

Inkjet tests have the particular advantage of being hygienic because they do not require urine collection, which facilitates testing in a location that is convenient for you. To get the result, you need to substitute the test under the stream of urine. If there is a hCG hormone in the urine and after a few minutes you can see the second strip that appears, indicating the existence of pregnancy.

Digital Tests

Since development is observed in everything, therefore this direction medicine is not left out. Nowadays, digital (electronic) tests are increasingly being observed in pharmacies, which make it possible to accurately determine the presence of pregnancy.

The digital test has a similar principle of operation as well as inkjet tests and simple test strips - determining the presence of the hCG hormone in a woman's urine. This test can be carried out at any time of the day, while from the first day of the expected monthly result will be 99% accurate. Even before the delay of the monthly digital test gives reliable results. In this way, the day before the planned cycle, 95% of women determined their pregnancy, 2 days - 90%, 3 days - 82% and 4 days - 51%.

The main difference of this test is that in a short period of time it gives an accurate result. The test becomes active after the absorption of urine by the absorbent strip has occurred, then an hourglass is observed on the screen. The result is displayed for three minutes. The indicator "+" indicates the presence of pregnancy, "-" indicates its absence. It is the fact that there is no other option in this test that makes it unique. At the same time, the obtained results are saved on the screen for up to 24 hours. Reuse of the digital test is not provided.

However, obstetricians and gynecologists argue that any test cannot give an accurate confirmation of the presence of pregnancy. Since with some express diagnostics the second strip may appear weakly, in order to accurately confirm the existence of pregnancy, you should undergo an examination by a gynecologist, who will certainly give an unambiguous answer.

Reason for incorrect result

Using an expired test or performing the test incorrectly are the main causes of a false result. Sometimes in the early stages of pregnancy, the concentration of hCG can be quite low. This is due to the fact that the fertilization of the egg in some women occurs later, thus the concentration of hCG occurs later, so this hormone test cannot determine and provides a negative result.

It is recommended to retest after a few days. Therefore, for convenience, some manufacturers sell two test strips in a package. To confirm the result, it is desirable to use tests of different brands.

False positive results are displayed on the test much less frequently than false negative ones. If a woman has used drugs containing hCG, such as Profazi or Pregnil, then there is a high probability that the test will show a false positive result. In this case, the test should be carried out 14 days after the use of the drug. False-positive results can be shown if the woman's body has a tumor that produces hCG (cystic mole or chorionepithelioma).

In the case of an ectopic pregnancy, the test result may be positive, but it may appear late, since in such a pregnancy the concentration of hCG is lower, so the result reaches the required test level later. If there is a threat of miscarriage, the level of hCG concentration is also reduced, the test result may be negative. It is worth considering that if the test shows negative after a positive result, then this may be a sign of a miscarriage. The test may show a positive result within 2-3 days after an abortion or induced abortion.

In women suffering from kidney disease, test results may be falsely negative, the reason for this is a violation of renal filtration, therefore, metabolic products, in particular the hCG hormone, are excreted from the body with urine. in atherosclerosis of the aorta, heart failure and arterial hypertension there are also violations of renal filtration.

On a poor-quality test, blurry spots may appear instead of the second strip, which are considered as a false positive result. Stress, alcohol, lactation, taking birth control pills and other medications, in addition to the above, do not affect the test results.

Do not forget that the test will only help determine the existence of pregnancy, but will not show whether its condition is normal. Therefore, the test does not replace the examination of the doctor.

Modern pregnancy tests are very affordable and easy to use. Each of them (depending on the type and manufacturer) may have a different instruction from the others. But most of the same type of tests are applied in the same way. True, for each type of test - its own way of application:

Instructions for test strips:

Open the package and take out the test strip.
Collect the urine in a clean, dry plastic or glass dish and place the test in the urine to the level indicated by the arrows for 5-10 seconds.
Remove the test from the urine and place it on a flat, clean, dry and non-absorbent surface (such as the top rim of a urine collection cup).

Instructions for test cassettes:

Open the package and remove the test cassette with pipette.
Collect the urine in the included cup.
Using a pipette, drop 4 drops into the rounded window of the cassette.
Evaluate the result after 1-5 minutes, but no later than 10 minutes.

Instructions for midstream test (inkjet tests):

Take the test out of the bag.
After removing the cap and holding the test by the handle, place it in the urine stream for 5-10 seconds so that the liquid falls on the absorbent surface indicated by the arrow on the test (alternatively, you can collect the urine in a clean, dry dish and immerse the absorbent surface in the urine for 5-10 seconds). 10 Seconds).
Close the test cap and place on a flat surface.
Evaluate the result after 1-5 minutes, but no later than 10 minutes.

To ensure the highest efficiency of the procedure, it is necessary not only to follow the instructions exactly, but also to know when to take a pregnancy test and.

Notes

The packaging of the test is airtight and should be opened immediately before analysis.
Do not use the kit if the bag is torn or poorly sealed.
Each pack of dough is for single use only.
The kit is for external use only. Do not swallow (do not take by mouth).
Do not use the kit after the expiration date.
Accurately follow the time requirements of the analysis. To do this, it is best to have a watch with a legible dial or an alarm clock on hand.

Practice shows that on the first days of the delay, the second band appears weakly and after a longer period than they write on the packages. But for long periods it manifests itself faster and brighter than the first.
If the kit contains a second test, or if you bought another kit, wait a few days before testing again.
Appearance even

With the invention of tests for early, and most importantly, simple determination of pregnancy, women can become happy earlier than the prescribed 6-8 weeks. interesting position when the gynecologist confirms the fact of the development of a new life.

Two cherished strips bring a lot joyful emotions future parents. In this article, we will talk about all the intricacies of home express pregnancy diagnostics, teach you how to do the test correctly and understand the result.

How does the test work?

All tests are based on a single mechanism - the determination of the hormone chorionic gonadotropin or hCG in the urine, the production of which begins from the moment the villi of the growing placenta enter the uterus, i.e. attachment of the embryo. Every day its quantity is growing, but at the very beginning, the growth of this hormone can only be determined by a special study of venous blood (the result will be positive 5 days earlier than the most sensitive tests begin to strip).

The sensitivity level of most rapid tests starts at 25 mUI hCG. Some manufacturers write on the packages that the test is sensitive already at 10 mUI hCG, but this is difficult to prove. As pharmacists say, this is more of a publicity stunt than the truth. Another tricky advertising ploy is the inscription that the test has the highest probability of determining pregnancy before a delay, an accuracy of 99.5-99%, etc.

If you have a regular menstrual cycle

The release of a mature egg, ready for fertilization, falls in the middle of the cycle. With a 30-day cycle, this is the 15th day, with a 28-day cycle, the 14th day. Within the next two days, fertilization can occur. After the fusion of the egg with the sperm for another 4-5 days, it “floats” to the placentation site in the uterus. Those. at about day 22 of the cycle, a blood test can already see a growing hCG. The most sensitive and high-quality tests can show 2 strips even 4 days before the expected period, when the level of hCG in the urine becomes more than 25 mUI.

Thus, you can do a highly sensitive test on the 26th day of the cycle with a 30-day cycle, and on day 24 with a 28-day cycle!

If you have an irregular menstrual cycle

To determine when ovulation occurred, you can use:

increase in the level of basal temperature;
appearance .

Having designated for yourself the date of approximate ovulation, 12 days are added to this number - you can already detect an increase in hCG in the blood (see). 15 days after approximate ovulation, you can do a test with high sensitivity.

What time of day should you take a pregnancy test?

As a rule, the instructions for the test strips do not recommend what time of day to test. This means that during pregnancy, the test will show 2 strips at any time.

Gynecologists also advise doing the test in the morning, using night urine. In this case, the result will be reliable, especially in early pregnancy. If you test during the day, there is a possibility of an error, since the urine is not as concentrated due to the liquid consumed during the day. The same is possible if you do the test in the evening - the content of hCG in the urine will be less. If there is a need to test during the day, then it is better to do this after a four-hour abstinence from urination, while limiting fluid intake to obtain more concentrated urine.

General rules for the correct use of pregnancy tests

The pregnancy test must be stored under the conditions specified by the manufacturer on the package;
The packaging with the dough must not be damaged;
Expired tests cannot be used;
You cannot use the same test 2 times;
It is best to test on night urine;
The packaging with the dough is opened immediately before use;
Before urinating, you should wash yourself and dry yourself with a towel;
Urination should be carried out in a clean container;
It is very important to strictly follow the instructions: dip the test into the urine exactly to the indicated level, keep it in the urine no less and no more than the recommended time, evaluate the result only at the indicated time.

Pregnancy test - instructions for use

Pharmacies sell a variety of tests. All of them have different cost, but equally promise the exact result. We will figure out how to use them correctly and which ones will still be the most reliable.

The most popular and reliable are Frautest and Evitest pregnancy tests. The tests of these German manufacturers occupy an average price niche (100-140 rubles), but do not sin with false results.
All other tests can be considered equally reliable if used correctly, especially the time to delay. The most reliable result can be obtained by testing in the first 1-3 days of a missed period.
The cheaper the test, the cheaper the reagent that is used in it.

Strip test

Popular and inexpensive tests in the form of a paper strip coated with a layer of antibodies in hCG. The hormone contained in the urine reacts with the impregnation of the strip, and a second strip appears on the test.
Instructions for using the test. For testing, you will need a clean container in which a few milliliters of urine is collected. The test is lowered with the tip into the urine to the designated mark and held for 10 seconds. The result is evaluated within 1-10 minutes (the less hCG in the urine, the later 2 strips will appear).
Reliability - from the first day of delay.
Pros: cheap.
Cons: not convenient to use, does not show the result before the delay, may be wrong.

Can there be a negative pregnancy test result?

HCG levels rise differently for everyone. Within 2 weeks after the delay, the test may still be negative if the woman has endocrine dysfunction or a threatened miscarriage. False negative test also will be if it is used too early, some women begin to do tests from the day of a possible conception. Well, there is nothing harmful in this, but is it worth tormenting yourself, expecting a miracle?

Another reason is non-compliance with the rules for using the test.

False positive test result

This happens in the following cases:

in the first 2 months after delivery;
ovarian dysfunction;
the development of a hormone-producing tumor (chorioncarcinoma,);
when using the test with expired validity.

Is the result of a test carried out during menstruation reliable?

For some women, menstruation may continue even during pregnancy. However, menstrual blood in no way affects the sensitivity of the test, so the result will be reliable. Even if a woman did a test in urine stained spotting, if it has the proper level hCG test will show bright 2 stripes.

Test results for ectopic pregnancy

At ectopic pregnancy is known to attach gestational sac occurs outside the uterus, usually in the fallopian tube. But hCG begins to be produced in this case too. A feature is the absence growth of hCG or a small stature.

Thus, a regular pregnancy test will show the same 2 strips. It is likely that the second stripe will be barely visible or more blurred than with normal pregnancy, yes and positive test will become only after the onset of a delay in menstruation.

A special INEXSCREEN test allows you to suspect an ectopic pregnancy a couple of weeks after the delay. Diagnosis is based on the detection of the level of the modified isoform in the composition of hCG, which in ectopic pregnancy is significantly lower than the prescribed 10% characteristic of normal pregnancy.

Test results for a missed pregnancy

If a clear, positive result obtained several times during the week becomes doubtful, and then the test shows only one strip at all, it is highly likely that the pregnancy is frozen. You should urgently visit a doctor.

How to decipher a dubious result?

A doubtful result occurs when there is doubt whether there is a second strip. It can be faintly visible, blurry or slightly translucent as if from the inside. Causes:

a low level of hCG, borderline with a minimum, at which the test becomes sensitive;
unusable test, non-compliance with testing rules;
a woman's great desire to see 2 stripes. Too often we wishful thinking.

What to do if the test showed a questionable result? Repeat it after a few days, and preferably 1-2 days after the delay.

Pregnancy test anti-rating

Unfortunately, it also happens that, with strict adherence to the rules for conducting express diagnostics, a pregnancy test shows a result that does not correspond to reality. false positives and negative results tests fail:
