When should I do a pregnancy test?

Pregnancy is an almost magical condition thatrequires maximum attention and responsibility from women. It is better if it is diagnosed as soon as possible. Exactly say whether a woman is pregnant or not, only a specialist can, and the occasion for treatment can be two cherished strips on the test. When should I do a pregnancy test?

To understand this, you need to know that you areis a test. In the simplest version, this is a paper strip impregnated in a specific place with a special substance that changes color when it reacts with the hormone of chorionic gonadotropin (HCG). It appears in the blood of every pregnant woman.

This hormone necessarily starts to be developed,when the egg is attached to the uterus. Theoretically, it is possible to determine pregnancy at this point, in practice, the concentration of HCG in the blood at this time is minimal, and will reach the required value only after a few days.

Experts do not advise doing a test onpregnancy before the delay of menstruation, too little chance of a positive result, even with pregnancy. However, much depends on the sensitivity of the test. The sensitivity can be from 10 to 25 mM / ml. Have you chosen your pregnancy test? How many days can you hope for a truthful result? With maximum sensitivity already on the 4th day from attachment of the embryo.

Usually this happens on the 7-10th day. If the attachment occurs on day 7, the required concentration of HCG is reached by 10-11 days. That is, purely theoretically, on day 11 the test can already show a positive result. But the probability of this is quite small.

It can very well be that the attachmentwill occur only on day 10, which means that the amount of HCG may not be enough. In this case, a reliable result can be obtained not earlier than 14 days after conception. In fact, this corresponds to the day when a woman should start menstruating.

So when do you need to do a pregnancy test? From the above, we can conclude that to do the test without waiting for delay, there is no sense, the risk is high to get a negative result, and be upset ahead of time.

But all these calculations are valid only for the test withhigh sensitivity. In the case of a less sensitive test, it is necessary to wait another week. Only then will the results be as reliable as possible. This is exactly how experts respond to women's questions when they need to do a pregnancy test.

Rely on the test is not worth it. For certainty, it is better to make them a few. And with the results you need to go to the doctor, and make a blood test for HCG. In any case, with a long delay in menstruation without resorting to a specialist, you will not be able to manage, even in the case of a negative test. First, each organism is individual, and for a number of reasons, the amount of the hormone in the blood and urine can seriously differ. In this case, the rapid test will give a negative result, even if the woman is pregnant. In addition, the test can be defective, this is rarely, but it happens. Secondly, even if pregnancy really does not exist, it is necessary to determine the reason for the delay. This may be associated with banal stress, but may indicate illness. It is necessary to start treating them as early as possible, since otherwise the consequences can be irreversible.

By the way, if a woman's period started inbut there are other symptoms that may indicate pregnancy, the test still makes sense, in some cases, menstruation in pregnant women continues for several more months.

I want to believe that this article gave a detailed answer to the question "When should I do a pregnancy test?" Still, early diagnosis of pregnancy is a guarantee of the health of a woman and a child.
