Presumably, everyone knows that two red lines on the pregnancy test stick represent pregnancy, but many times they will make mistakes. If there is no result in the correct time or the result of the pregnancy test stick, it will lead to the failure of pregnancy test. Below belowLet’s take a look at the result of how to use the pregnancy test stick and see the pregnancy test stick.
The pregnancy test stick is preliminary diagnosis of early pregnancy by detecting the chorionic gonadotropin (HCG) in the urine.HCG is a kind of glycoprotein produced by the placenta during pregnancy during pregnancy, which can be discharged from urine through glomerular balls.The fertilized eggs need to produce 6 or 7 days as soon as HCG, and the actual secretion starts is 11 days later.
If you need to detect it, it is recommended to be about 7 days before the ovulation period or about 7 days before the next menstruation.If you want to be more accurate, it is best to do an early pregnancy test in two weeks of menstruation.
The accuracy of the pregnancy test stick of regular brands is about 85%to 95%, not 100%accurate. Some diseased drugs may also lead to an increase in HCG concentration in the body, resulting in false positive results.
