Only one day passed from the delay of menstruation, and the woman already wants to quickly find out whether she is pregnant. Curiosity increases if the future baby is very welcome. For many years, all women have enjoyed an affordable and simple way of determining pregnancy at very early lines - this is a common pregnancy test. It is very good that it can be used even at home.
How does the pregnancy test work?
In a pregnant woman in the body there is a hormone - a chorionic gonadotropin, it affects pregnancy. This hormone appears and accumulates in the female body from the first days of pregnancy. Immediately the level of hCG doubles every day. The maximum concentration of a hormone becomes approximately on 10 weeks of pregnancy, then its level in a female body decreases.
There are several types of tests, each woman can choose either. This can be an electronic test (it is very expensive), an inkjet, a flatbed and a test strip.
All tests are divided into two types of sensitivity. Some can determine the concentration of the hormone from 10 mU / ml. Such tests determine pregnancy in a woman after 7 days, immediately after fertilization. Do not forget that fertilization occurs, as a rule, after conception. The remaining pregnancy tests are less sensitive, so determine the concentration of the hormone from 25 mU / ml. Such tests determine pregnancy in later terms.
Theoretically to confirm the fact of not pregnancy can be a sensitive test done on the second day after a delay in menstruation. That the test was more effective, it must be done correctly. Morning is the most favorable moment for the test. Experts say that morning urine shows the maximum concentration of hCG.
- First, put the test in the urine, and hold it for about 5 seconds;
- second, leave the test on a flat surface for three minutes and then evaluate the result;
- third, the test should show control strips, they indicate that the pregnancy test is suitable;
- the fourth, if the pregnancy test highlights two strips, which means that you are in position. And if one - fertilization did not happen.
Some women who have experience in the use of tests claim that very many tests are not effective. But, the quality test shows an accuracy of about 97%. An erroneous test can occur if you did not follow the instructions, or held it in the morning. It also happens that the test determines the wrong result if the woman is sick. Another important nuance - a pregnancy test determines a false-negative result, if it's too early to conduct. In the presence of pregnancy symptoms, undoubtedly, repeat the procedure with the tests.
Complexity can arise with the definition of an ectopic pregnancy - not always a test can show it. Therefore, with a delay in menstruation it is necessary to consult a gynecologist. Of course, the desire to quickly find out about pregnancy is always present. But quickly - does not mean reliably. If you are in doubt, it is better to wait a few days and then you will be able to draw the correct conclusions from the results.
