Pregnancy self-testing is usually done through early pregnancy tests. Women who want to know for sure whether they are pregnant or not can take an early pregnancy test, blood HCG (human chorionic gonadotropin), and ultrasound. Blood HCG and ultrasound need to be examined in the hospital, but if you want to test on your own, you can do it through the early pregnancy test. Specific operational steps to stay in the test pregnant women urine (morning urine is better) with test strips of early pregnancy diagnostic test strips marked with max inserted into the urine, the urine level shall not exceed the max line, 1-5 minutes to observe the results, after ten minutes the results are invalid. Result judgment, only in the white display area at the upper end of a red line for negative, in the white display area above and below the presentation of two red lines for positive, suggestive suggestive of pregnancy. The absence of a red line at the upper end of the test strip suggests that the test strip has failed or the measurement method has failed. The minimum amount of HCG that can be detected in urine by this method is 25 U/L. It is recommended that women go to the hospital for reconfirmation after testing themselves, as early pregnancy test strips may not be accurate.
