When is the most accurate time to use the pregnancy test stick?

　　The main principle of pregnancy test stick is to detect HCG value, that is, the value of human chorionic gonadotropin in one month of pregnancy. is pregnant female A hormone secreted by the body that exists in urine and blood. It usually appears in urine a few days after pregnancy. However, due to the small amount of pregnancy, it is not easy to detect at first, and it does not become more obvious until 10 to 14 days. Therefore, it is recommended to test 10-14 days after menstruation is delayed, and try to use the first urine in the morning for testing.

　　When is the most accurate time to use a pregnancy test stick?

　　The test is relatively accurate when one month pregnant or 7-10 days after menopause. When using it, you should choose the first urination in the morning for higher accuracy. Generally, HCG is released between the fertilized egg and sperm It takes several days to appear in urine after binding, and it takes a certain ratio to be detected. It also has something to do with the method used. If the method is used improperly, there will be errors.

　　Using a pregnancy test stick in the morning and evening may also have different effects on the results. Morning urine generally has the highest HCG value, so many instructions recommend testing when you get up in the morning, but this is not absolute. I would like to give you a piece of advice. Early pregnancy test strips are not the most accurate. There are times when the test is inaccurate. It is only used as a standard for preliminary examination. It is best to go Hospital Do an HGC check.

　　How long does it take for a pregnancy test stick to detect pregnancy? Some people have misconceptions. They can use test strips to test on the day they suspect pregnancy, or the couple rushes to buy test strips to test on the second day after having sex. The results are predictable. When using test strips, be careful. It takes a few days for the test strips to detect pregnancy. The couple took a test strip to test on the second day of intercourse. At this time, it is almost difficult to use a pregnancy test stick to detect whether they are pregnant. The result is often that the second horizontal bar does not appear, but this does not mean that there is no pregnancy. Choose morning urine for self-test at least 10 days after having sex. The concentration of HCG in the urine after getting up in the morning is higher. Sperm and egg combine to form a fertilized egg and enter Uterus It takes several days for implantation and embryo formation. HCG will not appear in the blood until several days after pregnancy, and because the amount is small, it may not be detected at the beginning.

　　How to use pregnancy test stick

　　When in use, tear the aluminum foil bag along the gap and take out the pregnancy test stick.

　　Wear the disposable plastic film gloves included in the box, hold one end of the handle of the pregnancy test stick tightly with your thumbs, and tilt the end of the urine suction hole downwards. Note that the observation side of the pregnancy test stick should face downwards, and the direction of the plum blossom pattern should face upwards.

　　Aim at the urine suction hole on the side of the pregnancy test stick to pee, let the urine pass through the urine suction hole, and maintain the urination time for 1 to 2 seconds (please note that when urinating, the observation window should be prevented from getting wet with urine! Otherwise the pregnancy test stick will be invalid)

　　Then flip the pregnancy test stick with the observation window facing upwards, and continue to hold the pregnancy test stick diagonally. When you see purple-red liquid crawling on the observation window, a purple-red line will appear on the observation window within 1 minute. The pregnancy result can be read after 1 minute, and the non-pregnancy result can only be determined after 3 minutes. The results read after 5 minutes are invalid! A urine sample taken at any time is suitable for pregnancy testing. If you are in the early stages of pregnancy, it is best to use morning urine.
