summary

In life, when many women have doubts about whether they are pregnant, they often use a pregnancy test stick for testing. In fact, whether the test stick is accurate or not is related to the choice of test time. Therefore, let's understand when the test stick is most accurate.

When is the most accurate pregnancy test

First of all: pregnancy test stick is commonly known as pregnancy test stick, pregnancy test film or pregnancy test card. Test principle: the so-called test is to use the hCG contained in the urine to check. Human chorionic gonadotropin (hCG) is a hormone secreted by pregnant women. This hormone exists in the urine and blood. The general pregnancy test is to use the reaction of single and multiple hCG antibodies in the device to combine with the antigen in the urine to determine whether pregnant or not.

Secondly: when using the pregnancy test stick to test pregnancy, it's better to get up in the morning and take the components in the urine for the first time for testing, because the hormone level at this time is the easiest to detect. If it doesn't work, make sure the urine stays in the bladder for at least four hours.

Finally: ovulation is about the 14th day of the menstrual cycle. Assuming that fertilization is successful at this time, it takes 6 or 7 days for the fertilized egg to produce hCG at the fastest time, and the pregnancy test stick is determined by measuring hCG in urine. However, hCG really began to secrete a large amount of hCG when syncytiotrophoblast began to secrete after implantation. It takes at least 11 days for a pregnant egg to be implanted. Therefore, the earliest 6 days, if you want to be more accurate, you can wait 11 days later, which is more accurate.
