How to use early pregnancy test strips

If a woman has some suspected early pregnancy symptoms and is not sure whether she is pregnant, she can use a pregnancy test strip to test her urine to see if she is pregnant, but it is best to go to the hospital to check, because the pregnancy test results are more accurate.

Pregnancy can be diagnosed at the earliest using early pregnancy test strips. When a fertilized egg implants in the uterus, a new hormone called chorionic gonadotropin is produced in a pregnant woman's body, which works to help maintain the pregnancy. This hormone can be detected in urine around 10 days after conception, and detection of chorionic gonadotropin in urine is usually indicative of pregnancy. For this reason, a method that detects chorionic gonadotropin in urine using a pregnancy test strip or the like is called a pregnancy test.

To test early pregnancy with early pregnancy test strips, you must use morning urine, because morning urine is more concentrated and hormone levels are higher. In order to increase the positive rate of the test, you should try to reduce the amount of water you drink the night before.

How long can early pregnancy test strips detect pregnancy

The working principle of pregnancy self-test using early pregnancy test strips is to detect the HCG value, that is, the value of human chorionic gonadotropin. This hormone is made by the placenta, and 10-14 days after conception, the body begins to secrete chorionic gonadotropin. After secretion, it will first appear in the blood, and then appear in the urine along with the circulatory system. However, due to the small amount, it is difficult to detect at first, and it becomes more and more obvious until 1-2 weeks of pregnancy. The effect is not good if it is too early or too late.

Note 1: Morning urine test is more accurate for newly pregnant women. But for women who have been pregnant for some time, urine at any time of the day can be used for testing.

Note 2: It generally takes about 7 days for a fertilized egg to implant, which means that pregnancy can be detected on the day of pregnancy (equivalent to 7 days after intercourse).

Note 3: After a 7-day delay in the menstrual cycle, or 10-14 days of intercourse, or as early as 33 days after menopause, if the early pregnancy test does not result in pregnancy, you can do another test 37 days after menopause .
