Pregnant test paper can not test out what is going on

Pregnancy test paper can not be detected because of premature test time, incorrect test method, test paper quality problems, other special circumstances, etc. 1. Test time After premature pregnancy, the body takes a certain time to produce sufficient hormone levels to be detected. If the test paper is used too early after conception, it may appear false negative due to insufficient hormone levels. It is generally recommended to test after a week of menstruation delay, when the results are relatively more accurate. 2. Test method is not correct If the test paper is not properly used, such as the length of urine immersion test paper is not enough, the time to read the results is too early or too late, etc., the results may be inaccurate. Read the instructions carefully and operate strictly according to the requirements. 3. Test paper quality problems Poor quality or expired test paper may not accurately detect pregnancy. When purchasing, choose qualified products from regular channels and pay attention to check the shelf life. 4. Other special circumstances Some diseases, such as ovarian germ cell tumors, may cause human chorionic gonadotropin levels to rise in the body, resulting in false positive results. In some special pregnancy situations, such as ectopic pregnancy, hormone levels may rise slowly, and may also cause the test paper to fail. In addition, if the urine is diluted, such as after drinking a lot of water, it may also affect the results. When you suspect that you are pregnant but the test paper fails, do not blindly draw conclusions. You can test again in a few days, or go directly to the hospital for blood tests, blood tests can more accurately detect pregnancy. If there are abnormal conditions such as abdominal pain, vaginal bleeding, etc., you should seek medical attention in time to clarify the cause and take appropriate measures.
