Time of detection: HCG generally appears in the urine a few days after the implantation of the fertilized egg, and it can only be detected when it reaches a certain amount, so for women with normal menstruation, it is possible to detect HCG in the urine after menstruation is delayed, and women with long menstrual cycles or abnormal ovulation can only be detected when they stop menstruation for 40-44 days.

3. Urine dilution: If you drink too much water before the test, it will also cause the urine to be diluted and lead to false negative results.

4. Pay attention to the length of the urine immersion test strip during the test, if the length of the urine immersion test strip is too long, it may make the test result difficult to judge.

5. Do not judge pregnancy based on the test results when you have recently had a pregnancy, because after the termination of pregnancy, such as after childbirth, spontaneous abortion and artificial abortion, HCG can continue to be positive.

6. Some diseases and drugs may cause false-positive results, and some tumor cells such as molar pregnancy, choriocarcinoma, bronchial cancer and kidney cancer can also secrete HCG.
