If a woman has a short period of menopause, such as around 40 days after menopause to test the urine pregnancy test paper, the results of the test at night are not as accurate as the results in the morning, the accuracy is around 80%-90%, because the urine at night has already been diluted, the chorionic gonadotropin level in the urine is low may be able to detect a positive result, and the results are not as accurate as the results in the morning. If a woman has been menopausal for a long time, more than 60 days after menopause, the chorionic gonadotropin level in the urine is already very high, and the result will be positive no matter whether the test is done at night or in the morning, and the accuracy rate is the same, which can reach more than 95%. When a woman’s menopause is short, it is best to use morning urine for the test, because the chorionic gonadotropin level in the urine is higher in the morning, and the test is able to detect pregnancy earlier for early diagnosis.
