2. Early pregnancy test strip self-test early pregnancy method, although it is the simplest and most convenient method to determine whether you are pregnant. The mechanism is the qualitative determination of human chorionic gonadotropin (HCG) in urine. However, you need to pay attention to these things when using it to get accurate results.

1. The time of detection. This is because HCG usually does not appear in the urine until a few days after the fertilized egg implants, and it does not appear until a certain amount is detected. Therefore, in women with normal menstruation, it is necessary to have delayed menstruation before detecting HCG in the urinary band.

Women with long menstrual cycles or abnormal ovulation should not be detected until 40 to 44 days after menstruation has stopped. And if your menstrual period is delayed for less than a week, you can't detect whether you are pregnant.

2. Urine dilution. Drinking too much stuffy water and diluting the urine can lead to false-negative results.

3. Morning and evening tests may have a certain impact 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. Pay attention to the length of the urine immersion test strip during the test. Sometimes, the length of the urine immersion test strip is too long, which can make the test result difficult to judge.

5. Do not judge whether you are pregnant 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 delivery, spontaneous abortion, and after induced abortion).

6. Some diseases and drugs may cause false positive results. Some tumor cells, such as molar pregnancy, 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, it is necessary to pay attention to the production date when buying roll-off reeds.

8. Do not use test strips that have been damp.

To get the right results, it's best to wait until your period is two weeks late. If the test is negative and menstruation does not occur after 1 week, another pregnancy dipstick test should be done.
