Does the pregnancy test paper have to be first-morning urine?

If a woman's menstrual period is delayed during her normal menstrual cycle, it may be an early pregnancy. The early pregnancy test can determine whether a woman is pregnant through her urine. The best way to use the early pregnancy test is to use the woman's morning urine. This is because the hormones in the woman's body are higher in the morning, and the chance of urine detection at this time is higher. Therefore, the woman's morning urine is needed for testing.

Does the pregnancy test paper have to be first-morning urine?

When using a pregnancy test strip to test for pregnancy, try to use the first urine in the morning for testing, that is, morning urine, because the hormone level is higher at this time and it is easiest to detect. After a night of sedimentation, the hormone level in morning urine is higher, so it is easier to measure and get accurate results. You can test in the morning, noon, afternoon and evening, but it will not be as accurate as in the morning. In order to get correct test results, women should be especially careful not to drink too much water to increase urine, as this will dilute hormone levels and lead to some erroneous results.

Pay attention to the following precautions when using pregnancy test strips.

1. If the pregnancy test paper you bought is stored for too long (more than 1 year), or the early pregnancy test paper is damp and not kept at normal room temperature (should not be refrigerated), it may become invalid and result in a false negative test result. So pay attention to the production date when purchasing.

2. If the pregnancy has just begun, or there is a possibility of ectopic pregnancy, the HCG level in the body is generally low. The test sample needs to be left to stand for more than 3 minutes (generally only 1 minute is needed), and it is necessary to carefully identify whether there is a weak positive - the color band in the test area only appears faintly.

3. After 3 months of pregnancy, HCG levels decrease and urine tests may sometimes be negative or weakly positive.

4. In extreme cases, such as hydatidiform mole and choriocarcinoma, the HCG level in the body will be too high and the urine test will not show a positive result.

5. A positive result does not mean 100% pregnancy. Because some tumor cells such as hydatidiform mole, choriocarcinoma, bronchial carcinoma and renal cancer can also secrete HCG, and there have even been patients with endometrial hyperplasia who tested positive for HCG.

6. Do not use test results to determine whether you are pregnant if you have had a recent pregnancy. Because HCG may continue to show positive for a long period of time after termination of pregnancy (after delivery, spontaneous abortion and artificial abortion).
