An expired early pregnancy test strip showing two lines may indicate pregnancy, or it could be a false positive due to the expiration of the test strip. It is recommended to visit a hospital promptly for further analysis, as detailed below:
Early pregnancy test strips are generally used to test morning urine. The chemical reagents in these strips react with human chorionic gonadotropin (hCG) in the urine, allowing for an initial judgment of whether a woman is pregnant. If the test strip has just expired, it may still be effective and provide accurate results. If it shows two lines and there is a delay in menstrual bleeding, the possibility of pregnancy is relatively high.
However, if the test strip has been expired for a longer period, its quality may be compromised, affecting the accuracy of the test results. This may lead to a false positive during testing, meaning that pregnancy is not actually present. To confirm whether pregnancy is indicated by two lines on an expired early pregnancy test strip, it is advisable to visit a hospital for a blood test to check hCG levels, which will determine the pregnancy status based on the test results.
