A positive pregnancy test is the reliability of different diagnostic devices. I got pregnant what should I do

Reading time: 5 minutes

Delayed menstruation is the main, but not the only sign of pregnancy. Symptoms can also serve as a signal: malaise, depression, toxicosis, sleep disturbance, and even increased basal body temperature. A special express test will help to determine more precisely at home. It will show if conception has occurred. The main thing is to decide correctly what to do after a positive pregnancy test if the strips show a false result.

Reliability of a pregnancy test

home test ep determines pregnancy by level hCG hormone in a woman's urine. To get the result, it must be immersed in urine and look at the reflected indicators - on the control strip, an indicator of pregnancy. Rapid tests are different types according to their functionality: some are highly sensitive and should only be substituted under a stream of urine, while others must be left in it for a while. It is important to follow the enclosed instructions exactly so that the indicator is reliable.

The reliability of the express test largely depends on compliance with the operating rules, but the result can also be a false negative / positive in such cases:

• the expiration date of the device has expired;
• the rules for storing the device were not observed;
• when not correct use;
• the test was taken too early;
• when taking drugs containing hormones or diuretics.

The device may not detect pregnancy in a woman who has kidney disease, urinary tract, of cardio-vascular system, abuses alcohol. It is worth noting that a home test often falsely indicates an ectopic pregnancy, so if you suspect it is better to consult a doctor and conduct an additional examination.

What is a positive pregnancy test

The indicators of home tests are based on the content of the hormone hCG (human chorionic gonadotropin) in the urine: if the egg is fertilized and it is fixed on the wall of the uterus, the hormone begins to be produced and its level rises. The device captures these actions and shows a positive pregnancy result. After fertilization, the concentration of hCG increases every day: the more time has passed, the more likely it is to correctly determine pregnancy. The optimal period is two weeks from the estimated moment of conception.

How many strips on a pregnancy test

With a positive result, almost all home rapid tests show two bright stripes. Moreover, it is not necessary that they be the same as in the photo in the instructions. Sometimes it happens that the test showed two stripes, but one of them did not fully appear: it has a dull color, is blurry or poorly visible, but this result should still be regarded as positive. If the second strip does not appear at all, the pregnancy test is negative, carried out ahead of time, the device is damaged or misused.

What to do if the pregnancy test is positive

Positive results mean that pregnancy is likely to occur, but to be sure, it is recommended to repeat the diagnosis again in one to two days. If the indicators match, then the first thing to do after a positive test is to contact women's consultation to the gynecologist: to confirm the correctness of the test and a little later to register. The doctor will conduct an additional examination, prescribe tests.

This must be done, regardless of whether a woman plans to bear a fetus and give birth or is going to have an abortion. Even on early stage may arise various deviations and treatment or mandatory interruption will be required if the fetus is terminally ill. For example, the main thing that a gynecologist will determine is the location of the fetal egg: if it is located in the uterus, this is the norm, but if in fallopian tube- This abnormal pregnancy, which is extremely dangerous for women's health.

How to check the results of a home pregnancy test

Some don't trust pharmacy tests and prefer more reliable methods, regardless of the results obtained. If in doubt, the tester readings can be double-checked in the following ways:

• The first thing you can do is to purchase a rapid test from another manufacturer or do another test in a couple of days. It is worth noting that there are folk ways home testing, but resorting to them is not recommended so as not to harm health.
• To show more precisely whether conception has occurred, a blood test for hormone levels will help chorionic gonadotropin person. In the blood of a pregnant woman, the content of the hCG hormone is significantly higher than in the urine, and such an analysis will be more accurate.
• The third way is to ultrasound diagnostics: traditional or intravaginal, the latter is considered more accurate. However, unlike a blood test, which determines conception as early as the tenth day, ultrasound will be effective no earlier than 4-5 weeks.

There are also external signs by which the gynecologist judges the presence of an embryo. With the help of palpation, the doctor examines the uterus and evaluates its size, the condition of the appendages. Examines the mammary glands, external genital organs and, by their condition, determines whether conception has occurred. In pregnant women, the labia swell slightly, acquire a bluish tint and become cool. It is important to remember that such an examination should only be trusted by an experienced qualified doctor, since exposure to the abdomen and internal genital organs at an early stage can adversely affect the embryo.

Positive test but no pregnancy

Many are interested in - can the test be false positive and why can it be wrong? Yes, sometimes it happens that the test results are positive, while other types of examinations indicate the opposite and the reason for the delay in menstruation is different. Such an indicator is called false positive test for pregnancy. All pharmaceutical devices for home use pregnancy is determined by the increased level of the hCG hormone in the woman's body. But there are other reasons when the level of human chorionic gonadotropin increases.

Reasons for a false positive test

A positive test in the absence of pregnancy may be due to the use of a low-quality device or its improper use. In such cases, you can purchase another analogue and repeat the procedure. Very often, women take stains of a dried liquid for a second strip, which look similar, so the result must be recorded no later than five to seven minutes after testing.

If everything is in order with the device and the results are repeated, then the problem is in the body. The level of hCG in the urine could rise due to the acquisition of characteristic diseases or after taking hormonal drugs, drugs containing human chorionic gonadotropin. The increased content of hCG in the urine of a woman keeps for some time after an abortion, miscarriage, removal ectopic pregnancy.

For which diseases is a pregnancy test positive?

In the human body, an increase in the level of hCG in the blood, urine can cause the formation of a cyst or a malignant tumor, and not only in women, but also in men. The most common female diseases that increase the degree of hCG is uterine chorionepithelioma and hydatidiform mole. Enhanced Level the hormone will accompany the course of the disease until complete recovery and gradually decrease after the elimination of the disease.

The use is the most accessible, simple and fast way check with the delay of menstruation, whether it really happened. Although these tests can be easily purchased at all pharmacies, women are very concerned about the reliability of their results, as well as the question of what to do next when a pregnancy test is positive. Let's try to figure this out together.

Operating principle

The basis of all pregnancy tests is to check the reaction to the level of human chorionic gonadotropin (pregnancy or) in urine. This hormone begins to be produced by the female body as soon as the fertilized egg is introduced into the wall.

This usually happens at 3-4 weeks from the start of the cycle and coincides with the expected start time. Therefore, it does not make sense to test for a fact before the expected delay.

Every day, its amount doubles, so every day the probability of a reliable result when testing urine for this hormone increases significantly. It is recommended to test for 4-6 days of cycle delay, the reliability of the results at this time is the best.

Important! Morning urine contains the maximum amount of hCG, so it is advisable to test for pregnancy in the morning.

In pharmacies, you can purchase the following types of pregnancy tests:

Most often, women use the strip - this is the most inexpensive and common form of testing, which determines the onset of conception with a 98% probability. Inkjet and electronic tests, although more convenient and sensitive, have a much higher price.

Are the tests wrong?

The probability of a pregnancy test error is very low, much more often women cannot always understand the result ( faintly colored stripe is already a positive result. And yet there are situations in which the test results are questionable.

Did you know? In the ancient Egyptian papyri that have survived to our time, it is reported that the Egyptians of that period determined by pouring their urine on grains of barley and wheat. When barley grains germinated, it was believed that a woman would have, wheat -. If the grain did not germinate, then it did not come. Modern laboratory research found that the grain moistened with the urine of a pregnant woman germinates in 70%, and when using the urine of a non-pregnant woman or a man, the grains did not really germinate.

Sometimes a pregnancy test is positive and shows the presence in its absence (false positive), or vice versa - it says that conception did not occur, but the woman still turned out to be pregnant (false negative).

false negative

The reasons for getting a false negative pregnancy test result can be the following:

• poor quality of the test, expired terms of its use;
• misuse of the test or its misunderstood result;
• using the daily portion of urine, not the morning;
• taking diuretics or food () on the eve of testing;
• short gestation period (less than two weeks); this situation often happens with irregular menstruation.

You can get a false positive pregnancy test by the following reasons:

When buying a test, you need to pay attention to the expiration date and carefully read the instructions. alcohol consumption, stressful situations, (except for the above drugs containing hCG) do not affect the results.

What to do with positive results

If the test showed 2 strips, a second test should be done in a couple of days, which will increase its reliability. When confirming the previous result, you need to go to the gynecologist.

Retest

The longer the period of absence of critical days, the more truthful the test will be. For the reliability of the result, it is better to purchase a special kit at the pharmacy from the very beginning, consisting of two test strips.

Conducting a second control test will make the result more reliable and cast aside doubts about the onset of conception.

This will be especially true for women with irregular cycle. Re-testing should be done two days after the first test. You cannot re-apply a test that has already been used.

It is not advisable to rush to do on too short term to confirm the reliability of the test without indications for this: symptoms of ectopic pregnancy, threatened miscarriage, suspicion of pathology.

Harm to the fetus has not been proven, but doctors recommend doing this procedure no earlier than the tenth week of the intended conception.

Did you know? A device for emitting sound at an ultrahigh frequency that is not audible to the human ear, that is, ultrasound, was first created by the British scientist F. Galton in 1876. At the beginning of the 20th century, doctors tried to use ultrasound to reduce pain in patients, but the results were ineffective. And in 1951, American scientists created a device for diagnosing internal organs- first ultrasound scanner. It was motionless and so large that the patient had to be moved along it.

Walkthrough of this medical procedure one hundred percent will confirm the presence or absence of conception. After the ultrasound, it is necessary to consult with the attending gynecologist.
Using the results of an ultrasound examination, the doctor will determine if there are any abnormalities during the onset, and check if the pregnancy is ectopic, if inflammatory processes and tumor formations in female organs.

Perhaps the most bad habit- it's alcohol. When a pregnant woman drinks alcohol, the alcohol passes directly to the baby through the placenta and can cause Negative influence on the development of the fetus, cause many deviations. In severe cases, fetal alcohol syndrome may occur.

Important! alcohol syndrome fetus (APS)- caused by the use of alcohol by the expectant mother, which is characterized by the appearance of mental and physical abnormalities that do not disappear with age. This is a violation of the activity of the brain (mental retardation, neurological anomalies, behavioral disorders), lack of height and weight, defects in the face and skull.

It is advisable to stop drinking coffee. If it is very difficult to give up coffee completely, then drink no more than one cup per day. Caffeine increases blood pressure, disrupts blood flow.

All this contributes to the disruption of oxygen supply and nutrients to the child. In addition, having a diuretic effect, coffee contributes to dehydration.
You should also limit sitting at the computer, refuse to constantly use mobile phone in favor of a relaxing holiday and walks on fresh air, do not forget to ventilate the room in which you spend a lot of time.

Accounting in consultation

For further monitoring and control, a pregnant woman needs to contact the antenatal clinic and become registered. When registering, registration does not matter. You must register for up to 12 weeks.

For the entire time of being registered, the doctor is responsible for the pregnant woman. The gynecologist gives the expectant mother an individual card for a pregnant woman and a woman in labor, as well as an exchange card.

IN exchange card records are kept of all the results of ultrasound, a description of the course of pregnancy is given.

doctor prescribes necessary tests(urine, blood, vaginal smear, etc.) and sends for examination to other specialists (endocrinologist, dentist, ENT, surgeon, etc.) to avoid complications during the period of bearing a child.
So, we learned that pregnancy tests give enough reliable result, but it is very dependent on the timing of use. Therefore, if the test showed 2 strips, it makes sense to retest before contacting specialists.

At the onset of conception, observation by a doctor and attentive attitude to your body will never be superfluous.

A quick pregnancy test is a great invention of mankind, no matter how pathetic it may sound. Everything ingenious should be simple.

Today you can go to a pharmacy, buy a test and have preliminary information almost immediately. Tests are available to everyone, they are of different types, manufacturers. Most popular firms for today:

• Frau test;
• Novatest;
• Bebicek;
• Evitest;
• Clearblue;
• BB test.

All of them have one thing in common: analysis can be done at home and get a reliable result for a very long time. early dates. A few drops of urine are enough. The mechanism of action is based on the detection of human chorionic gonadotropin (hCG). This is a hormone that stimulates the development of the rudiments of the placenta (chorion).

The test is positive, what to do next?

It happens that a woman cannot get pregnant for a long time, undergoes a lot of examinations together with her partner, sometimes - treatment.

Or if there was a tragic experience of miscarriage, fears drive into chronic stress with all the consequences. After all, we are talking about a desirable, long-awaited pregnancy! And then the test is positive!

So that disappointment does not lead to large-scale stress, it is worth calming down. There are three further paths:

1. Leave everything as it is and wait obvious signs pregnancy.
2. Conduct a re-analysis after two or three days and then go to the consultation.
3. Contact a doctor, take a blood test for hCG and undergo an ultrasound examination.

The second option looks the most advantageous. The tactics of behavior in the first case can provoke false pregnancy. The second method allows you not to be distracted by false positive results and not waste time on unnecessary visits to the hospital.

It is the third option that guarantees a 100% conclusion about the presence or absence of pregnancy. Ultrasound will reveal the ectopic location of the fetal egg. Early diagnosis in this case can save not only the ability to give birth in the future, but sometimes life.

If the good news is confirmed, let's hurry up to register for pregnancy and start a new one, happy life waiting for your personal miracle.

Benefits of Medical Surveillance

To get the expected test result is an incommensurable happiness for a woman. And only the beginning of a difficult but joyful journey. The fact was confirmed, now it needs to be strengthened by its further actions.

The sooner you register for pregnancy, the more likely you are to endure and give birth healthy child. Women with hard experience unwanted interruption pregnancy, know about it. If this is the first long-awaited pregnancy should not be taken lightly. modern medicine minimizes these risks.

Being under the supervision of specialists, you will get the opportunity to do everything necessary examinations, take tests, get advice from professionals, geneticists, ultrasound diagnosticians.

you and your future child You will be under full supervision. And this will relieve many of the problems that arise during pregnancy.

Moreover, in our time there is a choice: you can contact a public clinic or a private specialist you trust. Choose the maternity hospital where you want to give birth to your long-awaited child.

Risks of uncontrolled flow

By refusing to observe, you are exposing yourself and your unborn child to significant risks. The following complications may occur:

• ectopic pregnancy;
• infectious diseases transmitted from mother to fetus;
• skip the moment when placental pathology appears, which can be corrected;
• infect a child during childbirth with poorly sanitized birth canals;
• there are positions of the fetus in the uterus, in which physiological childbirth are impossible in principle;
• miscarriage is possible for reasons related to the pathology of the mother's reproductive system.

The doctor prescribes the necessary examinations, drugs and procedures, monitors the development of the fetus and your condition, correcting it.

False positive result

Sometimes a quick test shows two lines. But after that, menstruation occurs or a second examination refutes the result. A false positive test is misinformation that ruins your plans.

Do not trust the first indication of even the most sensitive testing. A false-positive result is possible if the test is expired, if the conditions for its storage and transportation are incorrect, or if there is a factory defect. Difficult, but you can do the testing itself wrong.

Therefore, it is desirable to carry out control after two days with a test from another company. Read the instructions carefully and follow them correctly. Wrong observance analysis procedures may lead to an incorrect answer.

A false positive rapid test result can be:

• if you have recently had a medical abortion;
• in case of operated ectopic pregnancy;
• after spontaneous fading of the fetus in the early stages;
• with some endocrinological disorders;
• while taking drugs containing hCG.

If a woman is aware of an abortion or operation, then the miscarriage may pass spontaneously, unnoticed by her, and the test will be false positive.

Such situations are connected with the fact that the body cannot abruptly stop producing hCG after the start of synthesis, and the presence of this hormone in the urine can give such an unreliable answer.

A false positive test can be:

• before the next menstruation, if a woman has an oncological disease;
• with cysts of the stomach and ovaries;
• with hormonal failure in the body of a woman.

Then hormones similar to hCG are produced in excess and a quick test may not distinguish between them.

Regarding menstruation, there are cases when they occurred in the early stages. It is impossible to refute pregnancy by this criterion alone.

Menopause and menopause

This period in a woman's life is associated with many problems. There is a failure of the cycle, irregularity of menstruation, restructuring of the body. It is difficult to determine whether there is a delay in menstruation or not. To endure and give birth at this age is not an easy task, the female body is no longer so strong and healthy.

Contraception does not give a 100% guarantee, pregnancy can occur in adulthood. If a woman is ready to keep it, she will make every effort to do so.

At unwanted pregnancy a quick analysis will allow you to find out the reason for the delay in time. With age, the risk of having children with pathology increases.

Therefore, if in doubt, it is better to use tests to determine pregnancy in the early stages. A positive test in such a situation is a signal to quickly consult a doctor and decide what to do next.

Abortion at this age will also not add health, in addition, for a woman with children and, possibly, grandchildren, it is psychologically difficult to undergo this procedure.

During menopause and menopause, there are also false positive tests.

This is due to the unstable production of human chorionic gonadotropin in the body. Due to hormonal changes, there may be bursts of hCG synthesis and this may show a sensitive test.

unwanted pregnancy

A positive test in an unwanted pregnancy is a tragedy for a woman. Don't despair right away. The test may be wrong. But if the result is confirmed, what to do?

Do not panic. Weigh the pros and cons. Make decisions wisely and responsibly. This is not only about your life and future, but also about the life of another living being, and only in your will is this decision. Set aside emotions, evaluate the dangers of abortion and the risks of further infertility.

Take into account the blood group. If you have rhesus negative, with each subsequent pregnancy, the bearing of the fetus will be more problematic.

Think carefully, is there such a good reason to cut off new life. If you are left alone, there is no help, the father of the child refused to solve the problem, study or too young age- It's hard, but it can be done.

Many women decide to give birth in critical situations for themselves and subsequently never regret it. There are really good medical reasons for having an abortion and the raw psychological trauma associated with violence when women cannot do otherwise.

In any case, listen only to yourself, this is your life, no matter how society pressures you. We need to take reproductive health seriously. Use contraception, follow the cycle, respect yourself. Let a positive test be your expected happiness.

• What to do if the pregnancy test is positive

Home test systems for determining pregnancy are very popular today, they are so simple and reliable to use - manufacturers talk about 98 and even 99% reliability of the results. If you are wondering what is wrong with that 1%, then here are five reasons why a pregnancy test can be false positive.

Home pregnancy test: how it works

Home pregnancy tests are based on determining the concentration of one of the hormones - human chorionic gonadotropin (hCG) in the urine. With the onset of pregnancy, the level of this hormone in the blood of a woman rises sharply, and it can be detected both in the blood and in the urine.

There are several varieties of home pregnancy tests, and usually the manufacturer gives clear and detailed instructions how to use them. So, some test strips need to be lowered to a certain level in a container with urine, while others need to urinate (or drop urine on contact zone test).

Depending on the choice of the manufacturer, a “+” sign, the words “yes”, “pregnancy” may appear on the test strip of a pregnant woman, but most often - two indicator lines. One of them appears in any case (this confirms that the test is working, and you followed the instructions exactly), the second - only with an increased level of hCG in the urine, that is, it indicates pregnancy. The second strip may be noticeably paler than the first, but still indicates a positive result. It is with these tests that women make the most common mistake.

Reason 1. Failure to meet the test check time

All tests have a time interval when the result should appear clearly and clearly - usually not earlier than 3-4 minutes after contact with urine and not later than 10-30 minutes after. If you look at the test later, after an hour or more, then for the second strip you can take the evaporation line - the border to which urine has risen along the test strip. After the dough dries, the dividing line becomes clearly visible, and it can be confused with an indicator strip.

Always strictly follow the test system manufacturer's instructions!

Reason 2. Recent miscarriage or abortion

After termination of pregnancy (natural or artificial) hCG level in a woman's body decreases, but, of course, not instantly. In some cases, it may take up to 35 days before the concentration of this hormone returns to normal, and the average time interval for establishing hormonal balance is 19 days. Of course, a pregnancy test during this period will show a false positive result.

If you have had a miscarriage or an abortion, you have used contraception, and your pregnancy test remains positive after three weeks, this is a reason to go medical examination. Part of the placenta may remain in the uterus, which continues to produce hCG. If you do not take any measures, then in the future it will lead to inflammation and serious health problems.

Reason 3. Chorionic adenoma (molar pregnancy, hydatidiform mole)

Rare in Russia (according to various sources, one case per 1000-3000 pregnancies) but quite common in the countries of the Far East (one case per 120 pregnancies) genetic anomaly, in which the maternal chromosome is “lost” during conception, and the non-viable embryo contains either only the father’s chromosomes, or a double set of father’s chromosomes and one mother’s. There may not even be a fetus at all, but at the same time, a pathological proliferation of placental tissue occurs.

This pathology is easy to detect when ultrasound examination, however, if a woman does not go to the doctor, then she may consider herself pregnant for some time: her stomach grows, she suffers from toxicosis, and the results of the test strip inspire confidence. However, chorionadenoma dangerous pathology, which can lead to strong uterine bleeding and the formation of a malignant tumor. Pathology is rare, but let's not forget about it!

Reason 4. Taking medications

The vast majority of medicines and food products(including alcohol) does not affect the results of a pregnancy test. The only exception is drugs that contain hCG (they are used to treat infertility). If you are taking these drugs on the advice of your doctor, you will need to choose another way to test for pregnancy.

Reason 5. Diseases

Various diseases can affect the level of hCG in the body. It changes when:

• premenopause or menopause;
• ovarian cancer, Bladder, kidneys, liver, lungs, colon, chest and stomach;
• kidney disease or urinary tract infection;
• ovarian cyst.

In addition, there is the so-called "phantom hCG" - the chemicals in the pregnancy test can react with them in the same way as with the hormone itself. What we are talking the doctor finds out about “phantom hCG” by determining the content of chorionic gonadotropin by other methods. If the results of different tests differ significantly (sometimes by dozens of times), then we are talking about just such an error.

Can pregnancy tests be trusted at all?

Can! But it must be remembered that there are very different different women and at different points in pregnancy. It reaches its maximum at 8-9 weeks after conception. If you're itching to hear about a positive result and you're trying to take a test before your expected period, you're very likely to get false negative result. It is much more common than false positive.

What to do if the pregnancy test is positive

If a pregnancy test shows a positive result, you must notify your doctor. Only a specialist can confirm if you develop normal pregnancy or the test gave a false positive result.

If the test shows a negative result, but you still think that pregnancy is possible, you should also consult a doctor.

The accuracy of the pregnancy test is high - 99%. But do not forget that someone falls into the 1% of exceptions!

According to medical news today

Although the test is considered authentic way definitions of an “interesting” position, however, the second strip does not always confirm successful conception. Causes false positive test for pregnancy are completely different: from banal (for example, non-compliance with instructions) to serious (health problems). It is always necessary to find out why a false determination of pregnancy occurred. If this result is caused by failures in female body, early diagnosis help deal with the problem as soon as possible. When it comes to women's health, any signals need to be checked.

There are several types of home tests. In pharmacies, this choice is usually presented:

• test strips;
• tablet;
• jet;
• electronic.

The most popular are test strips. Their advantages include ease of use, low cost. But this type of product also has disadvantages. It is inconvenient that urine must be collected in a container. Only morning urine is suitable for analysis. The appearance of two stripes indicates an "interesting" situation. Such strip tests belong to the first generation, so the results are not always confirmed.

Urine collection is required and tablet tests. Functionally, they differ from the strips by the presence of a submersible pipette. They are characterized by high sensitivity. However, from false positive result no one is safe.

At home, to determine successful conception, jet and electronic tests. They are convenient to use: neither one nor the other option requires urine collection. Captivating and high information content of the new generation of goods. The disadvantages include perhaps the cost: it is higher than that of analogues. But even when using modern options home diagnostics result is not always confirmed.

Mistakes in determining pregnancy at home happen quite often. The reliability of test results depends not only on compliance with the instructions, but also on the state of health. Despite possible risks receiving erroneous results, rapid tests are considered sufficient precise methods early definition pregnancy.

How do tests work?

To understand why a false positive pregnancy test appears, you need to understand the principle of action inherent in this type of product. The “work” of products, regardless of species, is based on a single principle - the reaction to hCG. Two stripes, the appearance of a plus or an inscription, a change in color - the reaction options depend directly on the type of product. But indicators that always determine pregnancy appear at a concentration of hCG.

The production of a hormone that allows you to identify a successful conception begins a day after the implantation of a fertilized egg. HCG levels are increasing daily. After a few days after the beginning of the formation of the chorion, the concentration of the hormone allows you to determine pregnancy. When planning a pregnancy, it is important to consider that fertilized egg fixed only after at least seven days. Time is also needed for the accumulation of the hormone. An express test can show a relatively reliable result with a delay, but not earlier.

It would seem that everything is very clear: if there is no chorion, then the hormone is not produced, which means that there is no pregnancy and there is nothing to determine. However, there are times when the results of a pregnancy test are positive, but there is definitely no pregnancy. Why is this happening? Many factors can influence these results. Not always a mistake is a cause for concern, but sometimes it indicates health problems. It is important to find out the reason for false testing. Only then can we talk about what steps should be taken in the future.

Prosaic causes of a false positive test

Prosaic reasons are one of the most common factors why false positive pregnancy tests appear, a pregnancy test may be overdue, the instructions for the procedure may be violated, and so on. To avoid such errors, you need:

• Monitor the expiration date of purchased products. When using an expired product, guarantees of a reliable result are minimized. The use of such a test is akin to divination on a camomile.
• Buy products from trusted manufacturers. It is necessary to focus not only on the recommendations of the pharmacist, but also to read the reviews first. Many women, for example, trust Evitest products, noting their high accuracy.
• Do a control check. No one is insured against a defective product, therefore, confirmation or refutation of previous results is required. The control check is carried out in a day or two. The second time, it is important to use a rapid test from another company.
• Strictly follow the instructions. Only with proper use can you get a reliable result. It is important to adhere to the rules for applying different types of tests, to withstand the time allotted for the procedure, etc. Even if it seems that everything is clear and without instructions, the first thing to do is open it. At least to make sure you're right.

The psychological aspect should not be excluded either. If a woman is really looking forward to pregnancy, then she can convince herself that there are two strips on the test. There are many such cases in medical practice. It may seem to a woman that the second strip is simply not so bright, but it is there. The desire to conceive a long-awaited child makes you rush things, wishful thinking.

If prosaic reasons, including psychological factor are excluded, then you need to look for other reasons for the appearance of a false positive result. Usually, if there are no signs of pregnancy, and the test shows two stripes, then you need to turn close attention on the state of health. Erroneous data can indicate both small malfunctions in the body and serious problems.

Health related reasons

The appearance of the second strip in the absence of pregnancy, women are usually attributed to improper home diagnostics. However, it is known that there are many factors that affect the occurrence of a false positive pregnancy test, and the reasons are not always banal. Often the second strip indicates health problems. False-positive analysis can be when:

• diseases of the small pelvis;
• miscarriage;
• violations hormonal background;
• tumor processes;
• menopause.

Women's health is no joke. Medical reasons false positive analysis is required timely diagnosis and subsequent treatment. A woman should be aware that a home testing error can be caused by health-related factors. Armed with knowledge, it’s easier to determine when to worry, which means it’s easier to not hesitate and make an appointment with a doctor.

False positive test after miscarriage

Can a test be false positive after an abortion or miscarriage? If an abortion occurs (regardless of the method), hCG ceases to be produced. However, the rest of the hormone is not immediately excreted from the body. The concentration of the hormone and gives a positive result, which, of course, cannot be true after interruption of gestation.

A similar situation occurs with an ectopic pregnancy. It often happens that a pathological pregnancy is removed, and the test shows two strips. The results are due to the high content of the “hormone of pregnancy” in the body. As soon as hCG is excreted, the simplest rapid test will give true results.

If the express test showed the notorious stripes, then this may indicate a biochemical type of pregnancy. With such a pregnancy, self-interruption occurs so early that the woman does not even know about her "interesting" position. However certain time after self-abortion, a high concentration of human chorionic gonadotropin is observed in her body, which is displayed on the express test.

Tumors and hormonal imbalance

A false result can be obtained if tumor processes are running in the body. Formations of various kinds produce hCG. Due to this factor, the test data may be positive, although in reality this will not indicate a successful implantation of the embryo at all. Elevated levels of hCG are observed as with benign neoplasms as well as in oncology. Most often, erroneous results are provoked by a corpus luteum cyst.

You should not immediately write off two strips for tumor processes. Inaccurate results can also be obtained in violation of the hormonal background. Sometimes the body begins to produce specific hormones that are structurally as similar as possible to hCG. The concentration of such hormones affects the results of home diagnostics.
