Often young women eager to know whether there was a birth in early pregnancy.Often, women are not waiting for delayed menstruation, run to the drugstore for a pregnancy test.And then they start to worry a popular question: when you can do a pregnancy test to get a reliable result?
How does a pregnancy test?
Method of work pregnancy test is very similar to the method tests to identify drugs in the body.Urine contains a number of different materials that react to special developers.In the body of a pregnant woman begins to dramatically produced a special hormone (hCG), which aims to identify all pregnancy tests.The presence of hCG in the blood - a reliable sign of pregnancy, so if the test is positive, the probability that you wear a future baby, equal to 99%.
When you can do a pregnancy test?
hCG hormone is produced very quickly, but the process only begins after implantation, which occurs 6-12 days after conception.Before implantation, the test will give a negative result.As a result, ultra-sensitive test to determine hCG of 10 IU / ml, can show a subtle strip of a second no sooner than 8-10 days of gestation.Average cheapest test with a sensitivity of 25 mIU / ml detect pregnancy after 10 days from the moment of conception, provided that implantation occurred very early.But to speak about the reliability of a negative result of the test can only be a couple of weeks from the date of conception.So, wondering what day to do a pregnancy test, count two weeks from the date of the alleged conception.
How to perform a pregnancy test?
Each test is accompanied by instructions, but some women make mistakes, trying to determine its position.Firstly, it should not touch the specific reaction zone on which are developers.Do not allow moisture on the test prior to use.Secondly, all the tests, except jet (midstream), can not be used in the jet of urine!Find any clean container, glass or plastic, which will help you in carrying out this procedure.Thirdly, note the test result in three to five minutes after use, as specified in the instructions.It is not necessary to wait 10 minutes or more, as during this time the moisture evaporates and the reaction layer damage.Often negative test shows a second strip through 11-15 minutes after use.The mistake would be to believe that you are pregnant, if called by the instruction time to be only one control line.The most appropriate time of day when you can do a pregnancy test with the most accurate results - morning.In the morning, the body of a pregnant woman contains the maximum amount of hCG hormone.It should be noted that the brightness of the second sheet is irrelevant.The weakest second strip shows your pregnancy if the test is performed correctly and you do not take special medicine containing the hormone.
If you have correctly calculated when you can do a pregnancy test, while the test gave a negative result to you, chances are that you are not pregnant is 90%.The remaining 10% - the probability of later implantation and slow growth in the number of hCG.Therefore, if a week after the negative result of menstruation and does not start, do the test again.In the false-negative test result may affect the kidneys to malfunction.
