How and when to make a pregnancy test

Often young women can not wait to find out whether a conception occurred at the beginning of pregnancy. Sometimes, girls, without waiting for a delay in menstruation, run to the pharmacy for a pregnancy test. And then they start to worry about the popular question: when can I do a pregnancy test to get a reliable result?

How does the pregnancy test work?

The method of working the pregnancy test is very similar to the method of tests that detect drugs in the body. Urine contains many different substances that react to special developers. In the body of a pregnant woman, a special hormone (hCG) begins to be produced sharply, all pregnancy tests aimed at revealing it. The presence of HCG in the blood - a reliable sign of pregnancy, so if the test is positive, the probability that you are carrying a future baby is 99%.

When can I do a pregnancy test?

HGH hormone is produced very quickly, but this process begins only after implantation, which occurs on the 6-12 day from the moment of conception. Before the implantation, the test will give a negative result. As a result, an ultrasensitive test, determining hCG from 10 mU / ml, will be able to show a subtle second strip no earlier than on day 8-10 of pregnancy. An ordinary cheap test with a sensitivity of 25 mU / ml will detect pregnancy after 10 days from the moment of conception, provided that the implantation occurred very early. But to talk about the reliability of the negative result of such a test can only be a couple of weeks from the day of conception. Therefore, considering what day to do the pregnancy test, count two weeks from the prospective day of conception.

How to perform a pregnancy test correctly?

Each test is accompanied by an instruction, however some women make mistakes, trying to determine their position. First, do not touch the special reaction zone on which the developers are located. Do not allow moisture to enter the test before using it. Secondly, all tests, except for jet (midstream), can not be used in a jet of urine! Find any clean vessel, glass or plastic, that will help you with this procedure. Third, pay attention to test results three to five minutes after use, as indicated in the instructions. Do not wait 10 minutes or more, because during this time the moisture evaporates and damages the reaction layer. Often a negative test shows a second strip 11-15 minutes after use. It would be a mistake to think that you are pregnant if only one control strip is shown through the time indicated in the instruction. The most suitable time of the day when you can make a pregnancy test with the most accurate result is the morning. In the morning in the body of a pregnant woman contains the maximum amount of hormones HCG. It should be noted that the brightness of the second strip does not matter. The weakest second bar indicates your pregnancy, if the test is performed correctly, and you do not take special medications containing this hormone.

If you calculated correctly, when you can do a pregnancy test, and the test gave you a negative result, the probability that you are not pregnant is 90%. The remaining 10% is the probability of late implantation and a slow growth in the amount of hCG. Therefore, if the menstruation has not started within a week after the negative result, take the test again. The false-negative test result can be affected by violations in the work of the kidneys.
