Pregnancy test stick is a tool used by women to detect whether they are pregnant or not, and it is also a convenient way to test pregnancy. Some women may have used it, but do you know the common sense of its use? If you don't know, come with me to find out.

First, the timing of pregnancy test with a pregnancy test stick. Generally, it is measured after menstruation is delayed for one week, and the result is more accurate.

Second, read the instructions carefully before use to check whether the pregnancy test stick has expired. Generally expired pregnancy test stick, although it will not be used like expired medicine. It may cause allergies, but it will affect the test results and lead to inaccurate results. So be sure to look at the shelf life before using it. Secondly, the incorrect use method will also affect the test results. Therefore, when you get a pregnancy test stick, you must read the instructions and follow the steps in the instructions strictly.

Second, if you want accurate results, it is best to use morning urine for testing. A pregnancy test stick verifies whether you are pregnant or not by detecting the concentration of human chorionic gonadotropin in human urine. After the morning urine is concentrated overnight, the hormone level is relatively high, which is relatively easy to measure. Of course, if it really doesn't work, make sure that the urine stays in the bladder for at least four hours before being used for testing.

Third, don't drink a lot of water to increase urine output. Drinking too much water will dilute the concentration of human chorionic gonadotropin in urine, making the results inaccurate.

Fourth, the pregnancy test stick is not 100% accurate. To be more accurate, you still need to see a doctor. The hormone level of human body is affected by drugs, diseases and other factors, which will make the pregnancy test stick appear false positive, so the results of the pregnancy test stick can not be fully seen at this time. In addition, when ectopic pregnancy occurs, due to the low level of human chorionic gonadotropin in urine, it may not be detected, or it is necessary to see a doctor for diagnosis. At the same time, if menstruation doesn't come suddenly, or doesn't come for a long time, but the pregnancy test shows no success, you should also go to the hospital for examination to prevent inaccurate situation.
