How to use early pregnancy test paper

When women use early pregnancy test strips, the accuracy is affected by the actual operation. If the actual operation is not good, there will be no accuracy. In addition, if the early pregnancy test paper shows a weak positive, it is very likely that you are pregnant. Generally, it will be more accurate to check with a test paper 7 days after the menstruation is delayed. If you check too early, there will be a certain deviation. If it shows a weak positive, it may be caused by a short pregnancy period. It is recommended to go to the hospital for an examination to diagnose whether you are pregnant.

Detailed explanation of pregnancy test strip application?

1. Be sure to read the manual carefully before conducting the test, and collect and restore the test reagents and urine samples to room temperature (20℃-30℃) before use. Remove the test strip from the original foil packaging and use it as soon as possible within 1 hour.

2. Insert the test strip into the urine sample collection hole in the direction of the arrow mark. Note: The urine level must not exceed the marked line on the test reagent strip. After at least 5 seconds, remove the device and place it on a clean, flat surface to observe the result. Wait for the dark purple band to appear. The test result should be loaded in 3 minutes and judged invalid after 10 minutes.

3. The accuracy of early pregnancy tests done at night will be affected to some extent, while using morning urine will produce more accurate results.

4. Many early pregnancy test strips indicate that women can do an early pregnancy test 1-2 days after missing their normal menstrual period. If the test result is negative and you still miss your period after a week, you should do another test.

5. If pregnancy has just begun, or there is an ectopic pregnancy, the urine to be tested needs to be left alone for more than 3 minutes (usually only 1 minute is needed), and careful identification is required to determine whether there is a weak positive, that is, the color of the test area is lighter than that of the comparison area, or it only appears vaguely.

When can pregnancy test strips be used for the first time?

1. Before explaining the initial use time of the pregnancy test strip, let's first understand the testing principle of the pregnancy test strip: Human chorionic gonadotropin (HCG) is a glycoprotein produced by the fetus during pregnancy and can be excreted from the body through the renal tubules. Therefore, measuring HCG in urine is a reliable indicator for diagnosing pregnancy. The pregnancy test paper adopts nano-colloidal gold technology and uses the chromatographic double-antigen sandwich method to test the HCG concentration in urine to determine whether you are pregnant.

2. All human chorionic gonadotropin (HCG) is produced by the transformed germ cells of the embryonic chorion. Its main function is to stimulate progesterone, which is beneficial to the continuous metabolism of estrogen and luteal copper to promote the formation of uterine decidua and enable the embryo to grow and develop perfectly. HCG begins to be secreted about 6 days after fertilization and reaches its peak in 60-70 days. Appreciate rapidly during the first 8 weeks of pregnancy to maintain the pregnancy. After about 8 weeks of pregnancy, HCG levels gradually decrease until they are relatively stable at about 20 weeks.

3. Therefore, theoretically speaking, the 9th day of ovulation is the 23rd day of the menstrual period. If you are pregnant, you can use a pregnancy test strip to check whether you are pregnant, but it is recommended to test it one month into pregnancy or 7-10 days after menstruation for relative accuracy. When using it, choose the first urination in the morning, which will be more accurate.
