Most of the time, early pregnancy test paper can let pregnant sisters know clearly whether the baby is coming or not. However, there are times when the presence of early pregnancy test paper is also the culprit that makes people tangle and die. Many people will be stunned to read this, why do you say so? I believe that many sisters will encounter such a situation, after taking a look: one deep and one shallow, is it a hit or not? The first thing you need to do is to take a look at the results. Is one deep and one light pregnant? What happened when the early pregnancy test paper was weakly positive? 1, early pregnancy test paper is weakly positive, if the pregnancy has just started, or there is a possibility of ectopic pregnancy (ectopic pregnancy), the HCG level in the body is generally low test samples need to be left for more than 3 minutes, and must be carefully identified on the early pregnancy test paper whether there is a weak positive, detection area ribbon only faintly appear. 2.Early pregnancy test strips may fail if stored for too long (more than 1 year) or if the test strips are not stored properly (e.g. damp) and are not kept under normal room temperature conditions with care, which may easily lead to false negative test results. 3.After 3 months of pregnancy, the HCG level decreases and the early pregnancy test paper test sometimes appears negative or weakly positive for early pregnancy test paper; a positive result also does not mean 100% pregnancy. 4.Weakly positive early pregnancy test paper, women of childbearing age who experience menopause or suspect pregnancy should not rely on just one early pregnancy paper self-test to determine whether they are pregnant. To be on the safe side, you can take another test after 3 days. Of course, the most reliable thing is to go to the hospital for a comprehensive examination in time, especially for those who are weakly positive, so that early measures can be taken. Some tumor cells such as staphyloma, choriocarcinoma, bronchial carcinoma and renal carcinoma can also secrete HCG, and we have also met patients with endometrial hyperplasia who have a positive HCG test. Is the early pregnancy test accurate or not? After preparing for pregnancy for so long, you should use the early pregnancy test to test if you are successfully pregnant. Wait a minute, is it accurate to use a morning pregnancy test? In fact, if you are doing a pregnancy test at home without any outside guidance, the test results are usually only 50% to 90% accurate. What affects the accuracy of the early pregnancy test? 1. The timing of the test. HCG usually appears in the urine a few days after the fertilized egg has been laid, and it has to reach a certain amount before it can be detected. Therefore, HCG may be detected in the urine of women with normal menstruation only after the delay of menstruation, while women with long menstrual cycles or abnormal ovulation may be detected only after 40-44 days of menopause. 2. Urine dilution. If drinking too much water makes the urine dilute it may lead to false negative results. 3. Doing the test in the morning and in the evening may have some effect on the results. Morning urine generally has the highest HCG value, so many instructions recommend testing in the morning, but this is not absolute. 4, when testing pay attention to the length of the urine submerged test paper. Sometimes the length of the urine submerged test strip is too long which may make the test results difficult to judge. 5. Do not judge whether you are pregnant or not based on the test results if you have had a recent pregnancy. This is because HCG can remain positive for a longer period of time after termination of pregnancy (after childbirth, spontaneous abortion and abortion). 6. Some diseases and drugs may cause false positive results. Some tumor cells such as gravida, choriocarcinoma, bronchial cancer and kidney cancer can also secrete HCG. 7.Do not use expired test strips. Because chemical reagents will lose their effectiveness after a long time, so pay attention to the production date when purchasing. 8, do not use the test paper has been damp.
