Some people suspect that they are pregnant when their menstruation is delayed, and then use pregnancy test strips to see if they are pregnant, but some people cannot use it properly, and the results are always different. In the early stages of pregnancy, growth hormone increases rapidly, but it also takes a process. Is it normal that the pregnancy test paper cannot detect it? Is it normal that the pregnancy test paper can't detect it? The principle of pregnancy test using pregnancy test strips is to test the hCG value, that is, the value of human chorionic gonadotropin in the body. This type of hormone is produced by the embryo and usually appears in the urine a few days after pregnancy. However, due to the small amount, it is difficult to test it at the beginning. It will not become obvious until 10 to 14 months. It usually takes about 7 days from intercourse to pregnancy. In other words, pregnancy can be tested on the same day, but the accuracy is not high. Generally, the test results will be more accurate if you test again 14 days after intercourse. Are early pregnancy test strips accurate? 1. Performing experiments in the morning and at night may have a certain impact on the results. The highest hCG value is usually found in the urine in the morning, so many instructions recommend testing in the morning when you wake up, but this is not certain. If you drink too much water and dilute the urine, it may cause a false negative result. 2. Testing time: hCG usually appears in urine a few days after embryo implantation, and it must reach a certain amount to be detected. Therefore, for women with normal menstruation, hCG can only be detected in the urine after the menstruation is delayed. Women with long menstrual cycles or abnormal ovulation can only be detected after 40-44 days of amenorrhea. If you think you are pregnant, in order to ensure the result is foolproof, the best way is to go to the hospital for a blood test. After all, it will be more accurate under the operation of professional personnel. In the early stages of pregnancy, you may not be able to detect it by yourself using test strips, because the results may be incorrect due to improper operation. Please read the instructions before operating. |
