Is the pregnancy test stick accurate?

Pregnancy test sticks are helpful for detecting early pregnancy in women. They can be detected about a week after the successful combination of the fertilized egg. The accuracy rate of pregnancy test sticks for early pregnancy detection is relatively high, about 85%. Pay attention to choosing pregnancy test sticks from regular brands. So, are pregnancy test sticks accurate? Let us understand this issue in detail.

First of all, we need to clarify some issues: ovulation occurs around the 14th day of the menstrual cycle. Assuming that fertilization is successful at this time, it will take at least 6 or 7 days for the fertilized egg to produce HCG. Pregnancy test sticks are determined by testing urine HCG. HCG actually starts to be secreted in large quantities after the fertilized egg implants, and the syncytial trophoblast begins to secrete large amounts of HCG. It takes at least 11 days for the fertilized egg to implant.

So, the earliest is 6 days. If you want more accuracy, wait until 11 days, as it will be more accurate then. You can make your own guess.

The pregnancy (positive) result can be read after 1 minute (30 seconds at the fastest), which means that if two lines are clearly shown after 1 minute of testing, it indicates a pregnancy (positive) result and there is no need to wait for 3 minutes before reading.

The result of not being pregnant must be confirmed after 3 minutes. This is because in the early stages of pregnancy, the HCG hormone content in the urine is very low, and a weakly positive result may appear during the test. The weakly positive result may not be displayed after 1 minute. As the reaction time increases, it will take 3 minutes for two lines to appear. At this time, the appearance of two lines should still be interpreted as a pregnancy (positive) result. If there is still only one control line after 3 minutes, it can be judged as a not being pregnant (negative) result.

The results judged after 5 minutes are invalid! This is because the results judged within 5 minutes are used as the experimental basis for designing products. The results judged after more than 5 minutes or even longer are not clear. Some people may have false positive results, and this result does not represent the actual situation.

Many women have doubts about whether pregnancy test sticks are accurate. If pregnancy is detected, in order to make yourself more at ease, you can go to a regular hospital to test whether you are pregnant through blood tests and B-ultrasound tests. I hope the above analysis will help female friends.
