Early pregnancy test paper is mainly used to check the value of human chorionic gonadotropin in urine to determine whether there is pregnancy, if the second bar is a white mark, it means that there is no pregnancy or the pregnancy is too short to be tested by early pregnancy test paper. 1. not pregnant: if the second bar of early pregnancy test paper shows a white mark, it is considered negative, i.e. no pregnancy; 2. pregnant: if the detection time is too early, early pregnancy test paper is too short to be tested. If the second bar of the test paper is a white mark, it may also be caused by the short period of pregnancy and the low level of hormones in the woman’s body. You can test the morning urine with the early pregnancy test paper after a few days to determine whether you are pregnant or not, and you can also test the blood HCG to confirm whether you are pregnant. Since there may be some errors in testing urine with morning pregnancy test strips, it is important to operate with care, inserting the urine in the white display area, and be careful not to exceed the MAX horizontal line. The test result with morning urine will be more accurate, and patients can also go directly to the hospital for blood HCG test if necessary.
