Female friends in the preconception period often use early pregnancy test strips for self testing, but sometimes they have already tested positive, indicating pregnancy. However, when they go to the hospital for examination and diagnosis, they find that it is a false positive reaction and they are not actually pregnant. So, under what circumstances does a pregnancy test result in a false positive?
1. There are many reasons why women may have false positives when using pregnancy test strips to check for pregnancy. Firstly, they should consider whether the purchased pregnancy test strip is a legitimate product, whether there are quality issues such as expiration, and also check whether the outer packaging of the purchased test strip is damaged, which may cause some chemical reactions in advance if the test strip is exposed to the air for too long. Under the influence of these factors, self testing results can result in errors and false positives.
2. If the product purchased belongs to counterfeit and inferior pregnancy test strips, the test results may not be accurate, which is also a common reason for false positive reactions in the test strips. Attention should also be paid during use, and it should be used according to the operating instructions, such as the time when the collected urine or test paper is placed in the urine, as well as the observation time. These are also important factors that affect the accuracy of the test results.
3. If women want to self test whether they are pregnant, they must purchase test strips from regular pharmacies or go to hospitals for testing in order to make the test results more accurate. If you have already purchased pregnancy test strips, please use them as soon as possible, especially after opening the packaging, to avoid prolonged exposure to air and false positive results during testing.
