Many women nowadays use early pregnancy test strips for testing, but sometimes errors or even inaccurate results may occur. Generally, it takes at least 10 days after sexual intercourse. It is still better to use morning urine tests, and you can also go to the hospital. Below, we will explain the health knowledge about early pregnancy test strips.
1、 Why do early pregnancy test strips fail
After pregnancy, the placenta secretes human chorionic gonadotropin (HCG), which can be detected in urine. And HCG is almost absent in the urine of non pregnant women. Early pregnancy test strips determine pregnancy by measuring the level of human chorionic gonadotropin (HCG) in urine. This type of detection has the advantages of being fast, convenient, sensitive, and highly specific. Early pregnancy test strips can only be used as a preliminary screening test, and should not be overly trusted, as testing with early pregnancy test strips may result in false positives or false negatives.
2、 Attention when using early pregnancy test strips
1. Experts in obstetrics and gynecology remind that when using early pregnancy test strips for testing, the usage method must be accurate. Before going to the bathroom for specific operations, carefully read the instructions on the test card and follow the instructions on how to use the early pregnancy test strips carefully. Otherwise, false positives are likely to occur, leading to inaccurate results.
2. Although early pregnancy test strips can provide some help to women, be careful not to blindly believe that they will give you the final answer. Due to improper testing timing and methods, self operation may result in inaccurate results. The results of early pregnancy test strips are not 100% accurate. To accurately determine whether one is pregnant, one should go to a professional hospital for HCG urine or blood tests to accurately determine whether one is pregnant.
The above is about the precautions for early pregnancy test strips. Generally, they can only be tested after a certain number of days, and some may be inaccurate. It is best to go to the hospital for a blood test for HCG. Some are due to psychological factors, because a slightly larger belly indicates pregnancy, and women also face a lot of pressure during the preparation period for pregnancy.
