Nowadays, many female friends use early pregnancy test strips to test whether they are pregnant after sexual intercourse, usually at least 10 days later. Early detection is also inaccurate, and it is important to pay attention to using test strips within 5 minutes. Below we will explain the issues related to using pregnancy test strips.
1、 Is the pregnancy test strip still effective after ten minutes
Generally, the results of early pregnancy test strips should be checked within five minutes, and a morning urine test should be conducted to check. It is recommended to draw blood to check for progesterone and HCG to see if there is pregnancy, and also to directly perform ultrasound to see if there are any abnormalities in the uterine adnexa. The test results are inaccurate after more than five minutes. If you are not confident, you can do a blood HCG test one week after sexual intercourse to basically determine whether you are pregnant.
2、 How to determine pregnancy through pregnancy test strips
1. Firstly, even if the pregnancy test stick displays two lines, it only indicates the possibility of pregnancy and does not necessarily mean pregnancy. Its accuracy is around 85%.
2. Secondly, the pregnancy test is performed by the test taker ten minutes after the urine test, and the result itself may have some inaccuracy, possibly due to the concentration of HCG in the urine indicating the pregnancy result. However, it cannot be ruled out that the misleading result of the pregnancy test may be caused by other air pollutants.
3. A purple red line appearing in the detection area within 1 minute indicates that the product is effective; It is recommended to read the pregnancy results of two lines after one minute for validity; The result of a pregnancy test showing that a line is not pregnant can only be confirmed after 3 minutes; If the pregnancy test result is read more than 5 minutes later, it is considered invalid.
The above are some usage methods of pregnancy test strips, and the timing needs to be carefully controlled. On the one hand, the test should be conducted at least 10 days after sexual intercourse, and the later the test, the more accurate it will be. Some district hospitals test HCG, but the accuracy is not 100%, and the results must be checked within 5 minutes.
