Strip strips with a sensitivity of 25 mME / ml, the cost is 30-40 rubles

These tests are popular among women because they are very accurate and do not require special conditions for use.

The test strips must be lowered into a container with a portion of urine up to the control line. The result will appear within 2-10 minutes.

Women's opinion:

Love:

I did this test three times, three days in a row, starting from the first day of the delay. At first, he clearly showed one strip, only one ... But !! After 2-3 minutes, a weak second strip was drawn, which could not be seen (if I had not been waiting for my pregnancy and had not considered these tests “under a microscope”). On the 5th day of delay, this test already showed two clear lines, and all doubts and worries disappeared by themselves.

Marina:

By the way, many tests “sin” with this - the stripes at the very beginning of pregnancy appear very weakly, almost imperceptibly. In particular, this was the case with the Vera test.

Ludmila:

I bought this test by accident, I just asked at the pharmacy “some inexpensive one”. On the third day of the delay, he showed a confident second line, and from the very beginning I had no doubt that I was pregnant. I left it for myself in the family album!

Women's opinion:

Julia:

It seems to me that the BIOCARD hCG test is the most sensitive, because it can predict pregnancy even before the delay. He showed me two strips after two days from the start of the delay - an excellent result, given the fact that this test Russian production. By the way, I did two tests with a difference of one day, and the Evitest test has not yet been able to catch my pregnancy.

The cost is from 15 to 35 rubles. This test for rapid (home) diagnosis of pregnancy leads in the sales rankings.

Women's opinion:

Ludmila:

A flimsy dough that falls apart in your hands even before use! I bought it because the pharmacy did not have the B-Shoors tests that I always used and trusted. The same test, when lowered into a glass of urine, drew in the liquid for so long that I spent several unpleasant minutes waiting for the result. Having received negative result, I did not believe this test - but, honestly, he did not lie about it. The next day I did another test, "Evitest", and only then was able to calm down.

Oksana:

I almost got a heart attack because two lines clearly appeared on the test the day before the expected period. The pharmacy told me that, unfortunately, errors often occur with these tests. I won't buy anything else!

Natalia:

I will never forget these thrill when two lines appeared on the test! By that time, we had a fight and parted with the young man, and I bought this test. To calm down and finally make sure that there is nothing left of him in my life. Convinced how! Two stripes clearly appeared on the test! I spent two days (it was a weekend) in tears and worries, and then I went to the doctor ... What do you think, what did the gynecologist tell me? That's right - I'm not pregnant!

Elena:

And I am satisfied with this test, because on the third day of the delay, he showed me the result - long-awaited pregnancy! Girls, test results can depend on many factors. I can’t judge how often this test is wrong, but for me it told the 100% truth the first time, and I’m happy!

What pregnancy tests lie more often than others?

We talked about a wide variety of tests (domestic and foreign manufacturers) for determining pregnancy, presented on the Russian market. But large variations in the prices of these useful devices may not speak of their “veracity”.

Unfortunately, both expensive and cheap tests can be wrong , and these errors are all the more annoying because they are associated with such a subtle sphere as a woman's pregnancy.

Currently, there are many varieties of means for determining pregnancy. All of them are divided into types.

Types of pregnancy tests

Depending on the principle of using the test strip, the means that establish the presence or absence of pregnancy are divided into the following subtypes:

• classic test strips;
• jet tests;
• electronic devices;
• tablet devices.

Depending on the type of product, its price category changes.

Clearblue Pregnancy Test

IN Lately This brand has gained particular popularity among the fair sex. The manufacturer produces three types of test strips:

• tablet test;

General instruction

The testing scheme depends on which type of product you have chosen. If you purchase a Clearblue Pregnancy Test, instructions are always included in the package. It corresponds to the type of device you prefer.

It is recommended to test in the morning, preferably immediately after waking up. This applies to those cases where the study is carried out before the delay of menstruation. If you already have it, then manipulation can be carried out at any time of the day, convenient for you.

The Clearblue Pregnancy Test is over 99% accurate.

Consider in detail each type of product of this brand.

Tablet device for determining pregnancy

This product is manufactured in cardboard box along with instructions. Inside the box there is a vacuum package in which the Clearblue pregnancy tablet is located. A photo of this type of device for you can see in this article.

To get an answer, you have to follow the following steps. With clean hands take out the device. Collect a small amount of urine in a dry container. Lower the device into the container with the indicated end, having previously removed the cap from it. Wait ten seconds and cap the absorbent end. Place the test on a dry, flat surface and wait five minutes. After that evaluate the result.

In order to correctly read the information provided by the Clearblue Pregnancy Test, look through the small window. There should be a bright control line. Its presence indicates that you did everything right and the result can be trusted. There should be a test strip nearby. Her presence suggests that there is a pregnancy. If the line is missing, then you are not pregnant.

After ten minutes, the result is considered invalid, since moisture evaporates and a reagent may appear, which is located in the place of the strip indicating a positive result.

Inkjet device for determining pregnancy

This device is quite accurate and easy to use. In terms of popularity, it is only a few points lower than Clearblue.

The inkjet device for diagnostics is available in a large cardboard box. Inside you will always find instructions describing correct work with a test. The device itself is additionally packed in a vacuum bag.

In order to properly test, you need to do the following steps. Remove the protective cap from the device and place it under the stream of urine for five seconds. When the absorbent part gets wet, it will turn into bright color. If this happened, then you did everything right. If the tip remains white or not completely colored, then the amount of liquid was not enough. In this case, you need to collect an additional portion of urine within five minutes and place the absorbent tip in it for 20 seconds.

After testing, close the end with a cap and place the device on a flat, dry surface. Wait five minutes and take a close look at the machine. On it you will see two windows. The smallest should contain bright stripe. If it is, then the reaction has occurred and the test was carried out correctly. After that, look at the large window. In it you will see a minus or plus. Accordingly, a minus indicates the absence of pregnancy, and a plus indicates its presence.

Disregard the result after ten minutes as it may be a false positive.

Clearblue Electronic Pregnancy Test

The Clearblue Digital Pregnancy Test will not only tell you if you're pregnant or not, it will also set you an estimated time from the day you conceived if you get a positive result.

This model is produced in a cardboard box. Like its predecessors, the test is packed in a vacuum bag and is reliably protected from moisture.

In order to properly test, you need to perform the following manipulations. Remove the cap from the absorbent strip and place it under your urine stream for five seconds. If desired, you can collect the test material in a clean container and dip the end of the device into it for 20 seconds.

Next, you need to return the cap to its original position and put the device on a flat surface. Wait required amount time to result. While the reaction is going on, in a small window you can see hourglass. As soon as testing is completed, an image will appear. It should tell you that you are not pregnant, or show you the expected due date if you are positive.

Unlike its predecessors, the result of the study on an electronic device is available to you within one day after the manipulation. You no longer have to limit yourself to ten minutes and hastily evaluate the result. In general, you can conduct a test and go about your business, and when there is a free minute, calmly study the answer received.

That is why digital test for pregnancy has gained such great popularity among women, because he is many times superior to his "colleagues" and allows expectant mother find out about the presence of an "interesting situation" in advance. Also read what they mean.

The essence of the device

The clearblue digital test works on the same principle as standard test strips.

1. It reacts to the presence of gonadotropin in the urine of the expectant mother.
2. You can conduct a digital test at any time of the day.
3. Shows reliable information with an accuracy of more than 99% from the first day of the delay.
4. Even though affordable price, the clearblue digital pregnancy test is able to provide reliable data even before a delay occurs. For example, 4 days before the delay, more than 50% of women saw the result of "pregnant", 3 days - 83%, 2 days - 91%, and one day - 96%.
5. As women indicate in numerous reviews, if the pregnancy test gave a negative answer even before the delay, then it is necessary to re-test on the first day of the delay.
6. The main difference between a digital pregnancy test, in addition to the price, from standard strips is the inability to fantasize about the results. As soon as the urine is absorbed into the absorbent strip, the device starts working and an hourglass appears on the screen. It is this sign that means that the device is ready for use and starts working.
7. After 3 minutes, the symbol changes to “+” if conception has occurred, or “-” if conception has not occurred.

Deciphering indicators

Consider the main possible indicators digital pregnancy and ovulation test kliabl 7.

Instructions for use

Before conducting the study, it is necessary to adhere to a number of recommendations.

1. You can use the digital tool at any time of the day from the first day of the delay.
2. If you do research before due date- only morning urine should be used.
3. To get a more accurate reading of the indicator, you can always use only the first portion of urine.
4. Before the study, it is undesirable to drink a lot of liquid.
5. Be sure to read the insert before conducting the study.

From the date of the expected start of menstruation, the test can be performed at any time of the day

Now consider the procedure for obtaining a reliable result (the same actions must be carried out for a digital ovulation test digital):

• as soon as you are ready to conduct the study, remove the foil device and remove the blue cap;
• you need to start researching right away;
• the downward-facing sampler must be placed under the urine stream for 5 seconds;
• try not to wet the rest;
• then you may need to put on a cap and place the product on a horizontal surface;
• as soon as a flashing symbol appears, this means that the device is working;
• when the symbol stops flashing, the result will appear, if there is no flashing symbol, it means that you have used the device incorrectly;
• during the study, you can not hold the test with the sampler up.

Analysis of the result

Information about the gestational age is shown on the display next to the result

A digital ovulation test, just like a pregnancy test, is equipped with an indicator that displays the probable time from the moment of conception (ovulation). This information is on the display.

1. After 3 minutes, you can see the answer on the display.
2. If conception has occurred, the indicator may appear on the display until the gestational age is indicated. It is necessary to wait until the indicator stops flashing, and the expected due date of conception appears on the display. This may take 3 minutes.
3. Sometimes the result can be assessed after 1 minute.
4. The indicator is stored on the display for about a day.
5. If you are shown to be pregnant, you should contact your gynecologist for advice and recommendations on further action. The specialist sets the term of the "interesting position" from the first day of the menstrual cycle, and not from the date of conception.
6. As a rule, conception occurs approximately 2 weeks before the next menstrual cycle. The indicator showing the gestational age indicates only approximate information about the time from the moment of conception.
7. If we talk about the accuracy of determining the date of conception, then it is 92%. This probability is determined by the level of the main hormone of pregnancy in the urine. Hormone levels may vary different women, so the readings may not be accurate.
8. As for accuracy, it exceeds 99% when conducting a study from the first day of delay.

Analogues of such a device

The price of a digital clearblue digital ovulation test, as well as for determining pregnancy, is slightly higher than that of analogues. However, this is easily explained by the convenience of using such a device and the accuracy of the result.

There are several analogues this method definitions, e.g. tablet testers

Let's consider what analogues exist for determining the "interesting position".

Women's opinion

High sensitivity this tool provides the opportunity to use it four days before the start of menstruation

Consider the reviews of women who used similar devices and shared their opinion about their effectiveness.

Nadezhda Lubyanova:

My husband and I have been planning a pregnancy for over 3 years. It turned out that I have some problems with hormonal background so I had to undergo treatment. As soon as the therapy ended, I started buying digital ovulation tests to find the best time to conceive. I want to note that the price of such devices is quite decent, but for such a case I didn’t feel sorry for anything, especially in the pharmacy they said that these are the most accurate tests. As soon as I saw the result of the presence of ovulation, I immediately took my husband into circulation. I note that we continued to try for another 3 days after ovulation, since there is also a possibility of conception at this time. I couldn’t wait for my period, so I immediately ran to buy a digital test. When I saw how much it costs, I thought a little about whether it was worth taking it, the price was too high. However, the pharmacist said that only such a device could show the presence of an "interesting situation" even before the delay. So I didn't think twice and bought it right away. I took the test 5 days before the delay and saw the long-awaited positive result! I didn’t even believe it, so I began to do tests daily until the delay - and they were all positive! Now to anyone who can't wait for the delay, I recommend this particular device.

Alisa Stepanova:

I very often used the digital ovulation test digital, as there was a need to track ovulation. That is why I knew well the price of this device and its effectiveness. When my husband and I decided to have a baby, I also used this test so that the attempt was immediately successful. When I noticed in the calendar that I was already 3 days late, I went to the pharmacy for a test. I bought the simplest one, because I heard that after a delay, any device should already determine the state. The test showed a second line, but very weak - that's why I hesitated. I went again and bought a digital test, which immediately gave me a positive result. So sometimes it’s worth overpaying a little, but getting reliable information, and not spending money on numerous “cheap” ones.

Maria Gavrilova:

I used such a device once in my life, and it immediately gave me reliable information even a few days before the delay. The price, of course, is slightly higher than its analogues, but then I could afford it. Nice, easy test.

Long gone are the days when, in order to confirm your guess about the onset of pregnancy, you had to go to the gynecologist and donate blood or urine to diagnose the level of hCG. Now this indicator, which reflects the presence of a fertilized egg, can be determined with an accuracy of up to a milligram using an electronic test or its economy class analogue - test strips. Let's look at the types of pregnancy tests and how to use them. We will also compare digital devices with conventional ones in order to understand whether it makes sense to overpay.

Electronic pregnancy test. How pregnancy is determined using test systems

Diagnosis of the level of hCG helps many women learn about conception in the first days after the appearance gestational sac. This method is especially convenient when it is not possible to immediately visit the gynecologist's office. In addition, pregnancy tests are often used by women who have irregular menstrual cycle. In order not to constantly go to the doctor due to another delay, such a device helps to exclude pregnancy on its own.

The principle of determining pregnancy using a test is similar to diagnosis in a laboratory. IN female body there is a hormone called human chorionic gonadotropin. Outside of pregnancy, its maximum concentration is 5 mIU / ml. After fertilization, it begins to increase exponentially, starting at 25 mIU/ml and ending at 78,000 mIU/ml by the end of pregnancy. Depending on the hCG indicator gestational age is also determined.

In the laboratory, urine or venous blood is used as a biomaterial. Then, using a special reagent, determine hCG level. Pregnancy tests also contain a reagent that reacts to urine, and if it contains more than 25 mIU / ml of gonadotropin, the indicator shows two bars. In the absence of pregnancy, one control strip will appear on the test.

Types of pregnancy tests and how to use them

Pregnancy tests vary in design and sensitivity.

The degree of sensitivity of the test indicates what concentration of hCG it is able to determine. The pharmacy provides tests with sensitivity from 10 to 30 mIU / ml. The lower the value, the higher the sensitivity level of the test, that is, if you need to confirm pregnancy before the delay, you should use a test marked from 10 or 15 mIU / ml.

test strips

Strip tests look like a strip equipped with an indicator on one side. It must be placed in a container with urine and wait until it reacts.

How to use:

• Fill a clean container with urine.
• Open the package, and then remove the test strip.
• Hold the test strip and immerse it in vertical position into the urine up to the marked line.
• Soak the strip in the liquid for 10 seconds and pull it out.
• Between 3-10 minutes you will get the result. During this time, the control strip will turn first, followed by the test strip if the pregnancy has taken place.
• Fuzzy second stripe indicates short term gestation.
• The result after 10 minutes is not worth considering.

Test cassettes

Unlike strips, tablet-type tests are equipped with a plastic case with a small window for instilling drops of urine.

How to use:

• Remove the pipette and test device from the sealed container.
• Collect a portion of urine in a container.
• Fill the pipette with urine.
• Drop exactly 4 drops of liquid into the window.
• Lay the cassette in a horizontal position.
• After 4 minutes, the result will appear in a rectangular window.
• The test retains its information content for up to 10 minutes.

Inkjet pregnancy test

Such a device is also called a midstream test. It is very convenient, because you just need to substitute the device under the jet when urinating. This eliminates the need to collect urine in a container or use a pipette.

How to use:

• Remove the protective cap from the modular device.
• Hold the test cassette upright and place it under the urine stream.
• Put on the cap and put the test.
• After a few minutes (no more than 10), “+” / “-” will light up in the window.

Digital electronic pregnancy test

This is a modern, convenient electronic device. Pharmaceutical manufacturers even produce a reusable electronic pregnancy test with spare indicators. The test, in addition to the fact that the pregnancy took place, calculates the gestational age.

How to use:

• Remove the cap, place the open segment under the stream of urine for 3 seconds, without affecting the area with the window.
• A conditional clock will appear in the window, indicating the processing process.
• One of the following will appear on the display: "+"/"pregnant" or "-"/"not pregnant". If the test is positive, the estimated gestation lines will be additionally indicated - 1 or 2, 2 or 3, 3+ weeks.

Is an erroneous result of an electronic pregnancy test possible?

Electronic test pregnancy does not guarantee 100% certainty. There is always 1% false diagnosis. For test strips, the risk of an erroneous result is slightly higher and equal to 2-5%. In most cases wrong result is a consequence of some diseases of a woman or a banal non-compliance with the requirements in the instructions.

A false negative test may occur in the following cases:

1. The test was taken too early (hCG level has not yet reached 25 mIU / ml).
2. For the test, a non-morning portion of urine was used (the first few days after fertilization, the amount of hCG is negligible and is determined only in concentrated morning urine).
3. There is a history of kidney disease (it will be possible to determine hCG in venous blood, since it does not come out with urine).
4. Pregnancy proceeds with complications (threat of interruption, attachment of the fetal egg in the fallopian tube).
5. Before testing, the woman was abusing fluids or taking diuretics.
6. The pregnancy test is stitched or defective (if a control strip does not appear on contact with urine, it is better to use another test).

A false positive result occurs if:

1. You have taken pharmaceutical preparations containing gonadotropin, for example, Ovitrelle, Pregnil. This is possible if ovulation was stimulated, but conception did not occur.
2. There are neoplasms that synthesize hCG (tumor of the body of the uterus, pancreas, kidneys, etc.)
3. There was a miscarriage medical abortion, an operation to remove an incorrectly attached ovum in the previous cycle.

Note!

If the test showed two strips, you need to undergo an ultrasound to determine the location of the fetal egg.

If the test shows one line, but the delay exceeds 10 days and there are signs of pregnancy, you should donate blood for hCG at the nearest laboratory.

If the test is positive at first and then negative, it is likely that the fertilized egg is poorly fixed and came out with the subsequent menstruation. It is called spontaneous miscarriage and happens in 30% of cases, while most women did not even know about their situation.

Review of the popular Clearblue electronic pregnancy test

The range of pregnancy tests can hardly be called modest. Every year the variety of these devices increases, as well as the need for them. The Clearblue test occupies a special place in the market.

Below we consider the popular types of simple and electronic pregnancy tests, their prices and key differences between them.

Clea blue is considered the leader among all test systems. The test is made in Switzerland and, in addition to over 99% accuracy, it has a beautiful and ergonomic design, and some types are designed for reusable use.

Clear blue is an electronic pregnancy test that can give the same results as ultrasonography. The built-in smart sensor not only detects your condition, but also calculates estimated time gestation.

1. Clearblue Compact― the test of a delicate form with jet system. Gives clear data 4 days before the expected menstruation. The cost is 139 rubles.
2. Clearblue Plus― the jet test with the convenient curved case that provides correctness of carrying out procedure. The cost is 193 rubles.
3. Clearblue Digital- an electronic pregnancy test, which you can buy for 370-420 rubles. The hypersensitivity of the sensor determines not only the presence of pregnancy, but also its duration.

Using Clearblue makes it possible to get an unambiguous result - there is a pregnancy or not. This device does not provide for any dubious and weakly expressed strips and guesses.

On a note! The instruction of the electronic pregnancy test warns that the mark in the window is stored for 24 hours. Then the screen goes blank and no longer shows information.

How not to make a mistake when choosing an electronic pregnancy test

Regardless of whether desired pregnancy or not, the test is bought in order to determine the cause of the delay in menstruation. Of course, digital instruments show exact result already a decade after ovulation than primitive test strips, but they are also several times more expensive. But there is also a good choice among tests of an average price category.

In order not to make a mistake in choosing the Clearblue electronic pregnancy test, you need to follow a few recommendations:

• The accuracy of the results directly depends on the level of sensitivity of the diagnostic system. The higher the sensitivity of the test, the sooner and more accurately it identifies hCG in the urine.
• Wide famous brand is the key to a quality test system.
• A highly sensitive reagent is expensive, so cheap pregnancy tests cannot be highly reliable.
• An important condition for the quality of tests is the tightness of the packaging. Also, it should contain all the necessary information.
• Test kits are stored for two years, so it is important to consider the date of manufacture when purchasing.

All pregnancy tests operate on the same principle, but some may determine the cause of the delay in menstruation a little earlier, while others may be a day or two later. When choosing a test, give preference only to trusted manufacturers and be sure to perform all actions according to the instructions. Then your results will be reliable.

To determine pregnancy at home, there are special tests. And if before they were limited simple stripes, there is currently a wide choice of them.
