Many women know how easy it is to diagnose pregnancy on their own, even at an early stage - just use a pregnancy test.

It seemed that everything is quite simple, but this is far from the case. There are many nuances that should be taken into account in order for the result to be as correct as possible. Let's try to understand all the nuances that will tell you how to do the test correctly so that the result is reliable.

When to get a pregnancy test?

Most women are interested in the question, how many days must pass after conception for the test to show pregnancy? Of course, it is best to use the test after your period is late. Both gynecologists and manufacturers of express tests recommend using the test after the first day of delay.

But many women are eager to find out the answer to the question: "Is there a pregnancy or not?" and they start doing tests as early as a week after ovulation, that is, even before the expected start of menstruation.

Carrying out a test before the onset of menstruation can distort the result: the test can be both false-negative, the second strip may not appear at all, or it may appear barely noticeable, which will confuse the woman even more. That is why, in any case, it is worth waiting for a delay in menstruation.

If you do not have the strength to endure for so long, then it is best to take a blood test for hCG to determine pregnancy, the presence of the hormone in the blood will confirm pregnancy. You can take blood tests after 10-14 days. However, we note that you will have to pay for the analysis yourself.

What time of day is it preferable to take a pregnancy test?

The concentration of the hormone in the urine, to which the pregnancy test reacts, is at its maximum in the morning. Therefore, it is better to engage in self-diagnosis of pregnancy immediately after waking up in the morning. In the second or third month of pregnancy, this question is not relevant: you can do the test at any time of the day.

Many pregnant women try, with the help of pregnancy tests, to determine whether the pregnancy is progressing normally. I would like to immediately dissuade all women from such experiments. If you have any suspicions that the pregnancy is not proceeding as expected, or you have pain or discharge, then you should immediately consult a doctor. The test is not able to predict the threat of miscarriage or missed pregnancy.

The main mistakes that affect the correctness of the result

As mentioned above, earlier use of the test can affect the reliability of the readings. Also, the use of this diagnostic method outside the morning can affect the correctness of the test. Certainly, poor quality test that has been stored or transported incorrectly may also show an incorrect result.

Diagnostics should be carried out strictly following the instructions, that is, premature or too late evaluation of results may affect their correctness.

Remember that if a non-pregnant woman's test shows a positive result, then this is a good reason for a visit to the doctor, an increased level of hCG may indicate the development of some kind of disease in a woman, including cancer.

If you have done a test and are in doubt about its reliability, you can purchase a test strip from another company and try again to diagnose. To confirm pregnancy or lack thereof, you can also donate blood for analysis, go to an appointment with a gynecologist, or have an ultrasound scan.

Tests for determining pregnancy, of course, are very convenient, which is why every woman who is sexually active should be able to correctly diagnose.

In the life of every girl there comes a moment that can radically change her whole life, we are talking about pregnancy. You can stop burning with impatience, be tormented by doubts and learn about the birth of a new life even before visiting a doctor. To do this, it is enough to purchase a pregnancy test. And how to do the test correctly, what are they, their features, principles of action - we will talk below.

Varieties of pregnancy tests

In any pharmacy in the city, there is a huge number of different pregnancy tests, but according to the principle of action, all of them can be conditionally divided into three types:

1. A test strip is the most affordable and common option that you can use if your period is more than 10 days late. How to do it right: collect urine in a container and lower it into it paper strip.
2. The tablet test is not cheap, it differs from the first only in the method of use, since the reagent that detects the hormone in the urine is placed in a special container. How to do it right: the design of the test has two windows, in the first you need to drip a few drops of urine, in the second the result will appear.
3. The inkjet test is the most modern and the most expensive, the result is instant. How to do it right: no need to collect urine in a container, all that needs to be done is to bring the test under the stream of urine, it will immediately show the result.

All pregnancy tests work in the same way, they are used to detect the hormone in the urine - human chorionic gonadotropin (hCG), which is produced only in case of pregnancy.

Choosing the most accurate tests

Pregnancy has come or not, the girl wants to know for sure, so she tries to choose the best and most reliable test. Let's say right away that expensive and advertised is not always the right choice. Why? Because even the most common and inexpensive test will show a result with high reliability, if used correctly.

So, what you need to know and what to look out for before choosing and using a pregnancy test:

• expiry date plays important role in a reliable result;
• the integrity of the package (there should be no damage, dents, signs of opening, etc. anywhere);
• the higher the sensitivity in the test, the more reliable the result, this parameter is indicated by the manufacturer on the package (the most truthful are inkjet, they will show pregnancy even before the expected date of menstruation).

When exactly to take a pregnancy test

When exactly is it worth worrying, worrying and taking a pregnancy test to get an accurate result? We will answer right away that immediately after intercourse it is impossible to find out whether a pregnancy has occurred. The test can show the presence of the hormone "pregnancy" only 7-10 days after conception. It is also worth understanding that the level of the above hormone increases gradually, due to a low result (low sensitivity of the test), the reagent may show a negative result.

It is worth taking into account that highly sensitive inkjet tests are ready to correctly answer the question: are you pregnant a few days before the expected date of your period? Whereas simpler, inexpensive tests come after a few days of delay. To dispel doubts or, conversely, to enjoy the onset of the desired pregnancy, we recommend trying several different tests with an interval of 2-5 days.

Can tests be wrong

Pregnancy or not? Are you still plagued by doubts, even after having done a few tests? Recall that gynecologists insist that the reliability of pregnancy tests is from 95 to 97%, that is, such a procedure can be completely trusted.

At the same time, one should not forget that even perfect reagents and constructions can show incorrect results if they are used incorrectly. The test may also show an incorrect result if the girl (woman) has just been ill or suffers from diseases associated with hormonal imbalance. You cannot use tests for alcohol or drug intoxication, as the result will also be unpredictable. It should also be borne in mind that with an irregular cycle, the actual gestational age may be less than expected, and therefore the test may show a negative result.

How to do the test correctly

How to do a pregnancy test correctly so that the result is 100% reliable is a question that torments many girls. After all, the correctness of the result depends on the correct use of the test. Before proceeding with the procedure itself, you should definitely read the instructions that are attached to the test and are in the package. Usually, the test, regardless of cost and type, is fundamentally no different. The process itself is the contact of the reagent with urine.

We carry out a pregnancy test:

1. It is advisable to prepare a sterile plastic (available at the pharmacy) or glass jar in the evening.
2. In the morning (!), Just before use, and not the day before, remove the test from the package.
3. Collect the urine in a jar. Use freshly collected urine!
4. Dip the test (if the test strip is) into the jar up to the indicated line. Keep the strip in a container of urine for about 10 seconds (the instructions indicate a specific time).
5. Then remove the test and place it on a surface that does not absorb liquid.
6. After what time the result will be necessary to read in the instructions. On average, the wait takes no more than 1-5 minutes. Please note that after the specified time has elapsed, the result may be unreliable. As a result:
   • Positive test (pregnancy) - two red (pink) stripes.
   • Negative test (no pregnancy) - one red (pink) strip.

For a more accurate result, gynecologists advise doing a test at a time of day when the level of the hCG hormone is highest, that is, in the morning. Please note that if the gestation period is short, then the second strip may be mild. But even a slightly pink and poorly distinguishable strip indicates the onset of pregnancy, so you should not postpone a visit to your doctor.

So, today, a pregnancy test is a quick, convenient, anonymous way to find out if you are pregnant. It is easy to use, it shows high accuracy, and besides, the result can be found out a few days before the start of menstruation.

Girls, what tests do you use?

Millennials rarely use pregnancy tests: there is a growing understanding of how various methods of contraception work, and people on forums are discussing that now is not the right time to raise children. But if you are still ready to take on a lot of responsibility, it is worth knowing how to correctly determine whether you are really pregnant.

What are pregnancy tests?

The basis of any tests for determining pregnancy is a blood or urine test for chorionic gonadrotopin (hCG). This hormone is secreted into the bloodstream after fertilization, about 6-12 days after ovulation, and its amount gradually increases.

How can you make a test

If you are going to have a baby, it is worth checking your hCG level every two to three days after your cycle shifts. You can take a home pregnancy test or donate blood for hCG at the clinic. A blood test allows you to detect pregnancy earlier, and also to find out if it is proceeding normally - along with the level of hCG, other important indicators will also be determined. A small increase in the hormone, which is determined only by blood, can indicate that the pregnancy is abnormal, or even be a signal that the pregnancy is ectopic, so do not neglect this method.

How to choose a home test

If you want to get the most accurate and reliable pregnancy test done as quickly as possible, it is best to have it done by a doctor. But if you do not have the opportunity to make an appointment or are too impatient, when buying a test, pay attention to the sensitivity level indicated on the package. The higher the sensitivity, the more accurate the reaction, for example, an indicator of 10 mMU / ml will help to confirm pregnancy on the 10th day from conception, and 20 IU / ml on the first day of delay.

There are several types of tests: strip strips, tablets, inkjet and electronic.

• A strip is a small, long piece of cardboard that contains fibers with chemicals that react to HCG. Its cost varies from 30 to 150 rubles, and for the result it must be dipped for a while in a glass of urine.
• The tablet test has the same sensitivity, but a little more convenient to use: it does not need to be immersed in liquid, with a small pipette you can drop a little urine into the window and see the reaction. Its cost is from 100 to 400 rubles.
• The inkjet test can be used at any time of the day, and the particles located on it, in the presence of the desired hormone, are attached to the hCG, making it visually noticeable without immersion in liquid. Its cost can be up to 600 rubles.
• Electronic tests are also one-off, but the result is displayed on a small screen. Their cost varies from 350 to 1500 rubles, and the sensitivity is approximately equal to strip strips.

When to do the test?

Pregnancy tests should be done 10-14 days after ovulation. It should be noted that some girls ovulate at the end of their cycle, so a test done at 28 days will not be accurate for someone who ovulates on day 22.

If you do not know when you ovulated, or you have an irregular cycle, take the longest cycle as a basis. Alternatively, you can download an ovulation calculator app or consult your doctor so that he can tell you exactly how your cycle is going.

Follow the rules on the dough packaging. If you purchased the test in a damaged package, it may show incorrect values. Consider the expiration date, and also try to do the test in the morning, right after a night's sleep.

If the test is not a jet test, urine collection requires the use of a clean container. In addition, doctors recommend performing hygiene procedures with washing the external genitalia before testing.

Read the instructions carefully, test times or other specifics may vary from manufacturer to manufacturer.

How to understand the results?

A false negative result is possible if you do the test too early or did not read the instructions carefully enough. At the same time false positive test- very rare, and it can be caused by the appearance of tumors or ovarian dysfunction. If your test is positive, an ultrasound scan should be done immediately to confirm the presence or absence of pregnancy.

In some women, pregnancy is accompanied by menstrual discharge, similar in abundance, timing and manifestations to normal menstruation. As a rule, the discharge ends in the first trimester, although there are cases of continued false menstruation until the very birth. In such situations, it is recommended to resort to a blood test, although a home test can still be used - menstrual flow does not affect hCG levels.

The fair sex, both planning a pregnancy and girls who are not yet ready to have children, periodically do tests to help find out if fertilization has taken place. There are several effective ways definition of conception on early dates that show the most reliable result.

How to identify early pregnancy

It is possible to accurately establish the fact of conception only after the onset of a delay in menstruation. However, many women want to know about this earlier, so they resort to various methods that allow them to do this at home. At the same time, girls are driven not only by curiosity, but also by the realization that it is better to have an abortion at the earliest stages of pregnancy. Even if a woman wants to give birth to a child, it is also worth registering as early as possible - this increases the chances of enduring healthy baby and avoid all kinds of complications.

Checking is advisable only after implantation: until this time, the fertilized egg does not come into contact with the parent organism, so the latter does not yet know about conception and does not show any signs. How to find out about pregnancy before delay? An absolutely accurate answer can only be obtained from a doctor by donating blood no earlier than a week after the intended fertilization. Such an analysis helps to determine the presence of the hCG hormone in a woman's body.

If for some reason a girl does not want to go to the hospital, you can find out if she is pregnant using an express test, which is sold in every pharmacy. This method is also based on the detection of hCG in a woman. Experts advise not to stop using a test from one manufacturer, but to purchase several at once, since they all have different sensitivity and may not respond to the concentration of the hormone in the urine (this indicator is individual for each girl). It is worth remembering, however, that such products cannot guarantee an accurate result.

Basal temperature in early pregnancy

If necessary, you can easily find out if you are pregnant, and you can do this without a test at home. How to determine pregnancy by temperature? To get the most reliable result, you should keep a special schedule of basal temperatures for a couple of months. With its help, a woman can track the peculiarities of the temperature regime of her own body and, by its fluctuations in the early stages, recognize pregnancy.

How to get a pregnancy test done correctly? This method is suitable for those girls who are planning a pregnancy. You should start keeping the schedule 2-3 months before the expected conception. Using the basal temperature chart, you can choose the optimal time for pregnancy. A significant disadvantage of this method is that you need to scrupulously monitor your condition every day at the same time and record accurate readings in the form.

How to determine pregnancy at home? In the morning, you need to measure the temperature in the vagina using a thermometer. It is better to start keeping a basal schedule on the first day of your period. By temperature fluctuations, you can judge your hormonal state. As a rule, by the middle of the cycle, the basal temperature can rise up to 37 degrees or more, and then, if there was no fertilization, it returns to normal again. With a successful conception, the indicator does not decrease, which indicates the work of certain hormones in the female body.

Determination of pregnancy with iodine

This method belongs to the category of grandmothers, but according to reviews, it helps to find out about pregnancy before the delay in menstruation. Like any other folk remedies for detecting conception, he should not be unconditionally trusted. How is iodine pregnancy test done? To this end, you need to moisten a napkin / rag with urine, and then drop a little iodine on it: if the material turns purple, it can be assumed that the girl is pregnant, and if it turns blue, the test result is negative.

Determining pregnancy with baking soda

A baking soda pregnancy test will help you find out the reason for the delay. This folk remedy, in addition, with a high degree of accuracy indicates the fact of conception at an earlier date. How to take a pregnancy test at home? To do this, collect the morning urine in a sterile container, to which add 1 tsp. soda and observe the reaction. If the powder starts to sizzle, the result is negative, and if the soda settles to the bottom, fertilization can be assumed.

Determination of pregnancy using potassium permanganate

In addition to the above methods, a test with potassium permanganate can show a positive reaction when conceiving a child. The process is primitive and simple: it must be diluted in a glass with a woman's urine a small amount of chemical diluted with water (the liquid should have a medium saturated pink color). If the urine turns white, the detection of pregnancy with potassium permanganate gave a positive result.

Traditional methods of determining pregnancy

There are many signs indicating conception, but most women doubt their reliability. Unlike prophetic dreams and other superstitions, some folk ways definitions of early pregnancy are nevertheless more accurate and convincing. Most of them are based on the reaction of certain substances with urine, which changes its composition after fertilization. Which of the existing home pregnancy tests can you trust:

1. If you boil urine and immediately after that pour it into a clean container (preferably a glass one), you can judge a positive test result by the white flakes formed in the liquid.
2. Another proven folk remedy that can be used at home is the study of your heart rate. To do this, lie on your back, put your fingers on your stomach, dropping about 7 cm from the navel. If you feel pulsation in this zone, you can assume successful fertilization.
3. The fact that you are pregnant is indicated by vaginal discharge similar to those that occur with thrush. When such a symptom is accompanied by pains of the mammary glands, the likelihood of fertilization that has occurred increases.

Pregnancy is an important stage in the life of every woman. The correct definition of this exciting event is equally significant in the case of planned conception and its unexpected occurrence. Since it is especially important to determine the fact of fertilization as early as possible, modern express tests have recently become the main means for its initial diagnosis.

How pregnancy tests work

Diagnosis of pregnancy using a test is based on the detection of a special hormone in the female urine - human chorionic gonadotropin, the production of which actively begins on the 6th day after the fertilization of the egg. When a biomaterial containing hCG comes into contact with a reagent, a staining reaction of the indicator occurs, which is highly likely to indicate the onset of conception.

Chorionic gonadotropin levels begin to rise from 6-10 days after fertilization. Having reached its peak in the second trimester, its number begins to decline.

HCG growth dynamics

The reliability of the test and its ability to determine pregnancy at the earliest possible date directly depends on the level of sensitivity, measured in milli International units per milliliter - mMu / ml. In modern rapid tests, this indicator varies in the range of 10-25 mMU / ml. The lower given parameter, the more sensitively the indicator reacts, therefore, fertilization can be detected at the earliest stages (11-12 days from the moment of ovulation). A more accurate diagnosis can only be provided by a biochemical study of blood, since the concentration of hCG in it increases a little earlier.

The standard indicator of the test sensitivity of 20-25 mMU / ml with the maximum degree of reliability reveals an increased hormone level as early as 1-2 days of delay in the menstrual cycle.

Reasons for inaccurate determination of the presence of pregnancy

Despite the high degree of reliability of modern express studies, when determining the presence of pregnancy, false-positive or false-negative results can often occur. In each individual case, the reasons for the error may be different.

In rare cases, the test readings may be erroneous.

To reduce the likelihood of errors during diagnosis, it is recommended to repeat the test after 2-4 days.

Reasons for establishing a false positive test result:

• some diseases and malfunctions internal organs and the endocrine system, in particular - ovarian dysfunction;
• taking medications based on hCG within 2 weeks before the study;
• an attempt to diagnose pregnancy in less than 2 months after childbirth, miscarriage or abortion;
• expiration of the shelf life of the test or non-compliance with storage conditions (violation of the tightness of the package);
• the presence in the body of tumor formations that produce the hormone chorionic gonadotropin;
• skipping more than 10 minutes after the start of the diagnosis (for certain types of tests).

Factors influencing the detection of a false negative result:

• an attempt at early diagnosis carried out before the recommended time indicated on the package;
• disruption in the endocrine system;
• low hormone levels associated with individual characteristics a woman's body;
• violations of the diagnostic procedure;
• expiration date;
• non-compliance with storage conditions or violation of the tightness of the package;
• reception on the eve of the test of certain types of medicines.

Preparing for the test

At the heart of all existing species express tests is based on the principle of detecting hCG hormone in the biomaterial (urine).

Popular types of tests

In order to eliminate possible inaccuracies in determining pregnancy, it is advisable to follow several recommendations:

• use tests only of the correct expiration date, packed in airtight containers;
• opening the package should be done immediately before the test;
• rapid tests are for single use only. If, for some reason, the indicator gave incorrect readings for the first time, attempts to carry out diagnostics with it again do not make sense;
• the highest concentration of the hCG hormone accumulates in the body during the night, therefore, according to the instructions, a pregnancy test is best done in the morning;
• it is advisable to wash before urinating;
• collection of biomaterial is carried out in clean dishes;
• following the instructions, lower the indicator into the liquid only to the specified level;
• it is necessary to strictly observe the diagnostic time;
• compare the diagnostic results with the attached instructions for the pregnancy test.

With a long delay in the menstrual cycle in conditions when a pregnancy test shows a negative result, a blood test will help to identify the presence of the hCG hormone in the body.

Types of pregnancy tests

Regardless of the level of sensitivity, pregnancy tests also differ in design and method of application:

• strip strips - narrow paper strips impregnated with a reagent with antibodies to the hormone are considered the most popular and affordable type of test, which, despite its low cost, has a high diagnostic reliability.
• flatbed - are a modified format of strip strips enclosed in a plastic block with two windows.
• jet - similar to a mini-case, at one end of which there is an indicator that does not require collection of urine in a container, but conducts diagnostics upon contact with biomaterial during urination. The indication is displayed in a separate window.

Inkjet pregnancy test

• electronic digital - highly sensitive miniature devices with a simple system for collecting biomaterial, in which the result is displayed on a liquid crystal mini-screen. Certain types of devices are compatible with a PC and make it possible to determine the approximate gestational age with a high degree of probability. They are considered among the most expensive.

Pregnancy test: instructions for use

Since the classification of modern tests is based on the principle of diagnostics, each of the presented types has its own differences and application features.

The cost of the test does not directly affect its reliability.

Strip strips

Since the kit for these express tests does not include a special container for collecting biomaterial, it must be prepared in advance. You need to collect some urine in a clean, dry container and dip a paper strip into it for a few minutes to the mark indicated on its base. You can judge the presence or absence of pregnancy no later than 10 minutes later. A positive result is marked with 2 parallel lines, a negative one - one.

Pregnancy strip test

Tablet option

The tablet test kit includes a mini-case with an identifier, a special urine container and a pipette. Having collected the necessary portion of the biomaterial in a container, you need to draw a small amount into a pipette, and then apply a few drops to a special window. In no more than 10 minutes, the result in the form of one or two stripes will be reflected in the second window.

Jet view

Due to the absence of the need to collect liquid in a separate container, jet pregnancy indicators are considered one of the simplest and most convenient to use. To carry out the procedure, it is enough to place it under the stream of urine for 5 seconds. Diagnostics can also be carried out in the standard way by placing the tip in a container with biomaterial. The result will be displayed within 10 minutes (the time depends on the total level of the hormone) in the form of one or two strips. High sensitivity allows you to determine the presence of conception at the earliest possible date.

Electronic digital apparatus

The most modern and also expensive way to determine fertilization is the use of an electronic verification system. The tip of the filter is briefly immersed in urine and after 3-4 minutes the result is displayed on the liquid crystal display. This type is considered the most accurate, effective and convenient, but the inscription disappears after a day.

Diagnosis of deviations using express test

A simple pregnancy test system, carried out by a test, is able to reveal not only the fact of fertilization, but also various problems and pathologies.

Enhancement hCG level can occur not only during conception, but also in non-pregnant women, as well as in men. Such a deviation may indicate a number of serious diseases. Among them:

• tumor formations in the testes in men;
• pathologies associated with the formation of a tumor in the gastrointestinal tract;
• malignant and benign tumors in the respiratory and genitourinary system;
• molar pregnancy or hydatidiform mole;
• malignant trophoblastic tumor.

An increase in hCG levels is possible in men.

Of particular note are tests in which the second strip is clearly paler than the first. Such an indicator may indicate a reduced level of the hormone chorionic gonadotropin. This condition is possible in the early stages of conception or in cases with a frozen pregnancy.

If you have any doubts about your health, it is better to immediately consult a specialist.
