is not absolutely accurate, but it is generally accurate. You can see if YJ is pregnant, but this is not the absolute standard. The safest way is to go to the hospital for gynecological examination
5. It's basically accurate
6. The accuracy of regular pregnancy test is about 85% - 95%
first of all, we need to clarify some problems: ovulation is about the 14th day of the menstrual cycle. Assuming that fertilization is successful at this time, it will take 6 or 7 days for the fertilized egg to proce hCG at the earliest, 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 time is 6 days. If you want to be more accurate, you can wait 11 days later, which is more accurate. You can guess for yourself
the result of pregnancy (positive) can be interpreted after 1 minute (30 seconds at the fastest), which means that if two lines are clearly displayed after 1 minute, the result of pregnancy (positive) will be displayed, and there is no need to wait until 3 minutes before interpreting
the results of non pregnancy can only be determined after 3 minutes, because the hCG hormone content in urine is very low in early pregnancy, and weak positive results may appear ring the detection. Weak positive results may not be displayed after 1 minute. With the increase of reaction time, two lines can only be displayed after 3 minutes. At this time, two lines should still be judged as pregnancy (positive); If there is only one control line after 3 minutes, it can be judged as non pregnant (negative)
the result of interpretation after 5 minutes is invalid! The reason is that the interpretation within 5 minutes is used as the experimental basis for the design of procts, and the interpretation results after more than 5 minutes or even longer are not clear. Some people may have false positive results, which does not represent the actual situation.
