The pregnancy test paper has a gray mark after drying

If there is a gray mark on the pregnancy test paper, does it mean you are pregnant? The test paper has a built-in dark gray mark, which is not the correct way to observe the test paper. To use the test paper to observe and determine whether you are pregnant, the specific steps are to use a urine cup to collect fresh urine, soak the test paper in the urine, and take it out after the urine wets the test paper. Wait for about 1 minute and check whether there are 2 red bars on the test paper. Obviously 2 red bars are a strong positive, indicating early pregnancy, and dark red is a weak positive, indicating an abnormal early pregnancy. Abnormal pregnancy needs to be tested again. It is best to take morning urine for testing. The HCG content in morning urine is relatively high, and the test results are more accurate. Blood HCG test should be checked 7-10 days after intercourse during ovulation. If the HCG value of the blood test is more than 20IU/L, it can be roughly analyzed to determine the early stage of pregnancy.

How to use early pregnancy test strips?

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.

2. Remove the test strip from the original aluminum foil packaging bag and use it as soon as possible within 1 hour.

3. Insert the test strip into the urine sample collection hole in the direction of the arrow. Note: The urine level must not exceed the marked line on the test reagent strip.

4. After at least 5 seconds, remove the device and place it on a clean, flat surface to observe the result.

5. Wait for the dark purple band to appear. The test result should be loaded in 3 minutes. The judgment will be invalid after 10 minutes.

Although the test paper is convenient to use, there are also many common problems. In order to make the early pregnancy test paper test results accurate, objective, and less error-prone, women should pay attention when using it:

1. It is best to use morning urine for the experiment. Female hormones are higher due to morning urine extraction.

2. Urine samples should be collected and tested immediately, and urine that has been stored for a long time should not be used.

3. The purchased test paper cannot be stored for a long time. If it exceeds 1 year and is not stored under normal temperature conditions, such as being frozen or humid, it may become invalid and may easily lead to incorrect test results.

4. To improve the accuracy of the experiment, you should try to avoid drinking too much water every day before the test.

Mastering the above methods, the test results of early pregnancy test strips can be more accurate. Of course, early pregnancy test strips can only be regarded as the results of analysis and judgment. If you want to finally confirm the pregnancy, you have to go to the hospital for more professional examinations.

When should early pregnancy test strips be used?

It is generally recommended to test with early pregnancy test strips 10 days after the menstrual period is delayed, so that the result will be relatively accurate. Generally speaking, the first urine test in the morning will give more accurate results for women who are pregnant soon. But for women who have been pregnant for some time, urine at any time of the day can be used for testing. Yes, it usually takes about 7 days from intercourse to pregnancy. In other words, you can test whether you are pregnant on the same day. Female friends who suspect they are pregnant should remember that it is important to test whether they are pregnant at the appropriate time.

However, if you use blood HCG to detect early pregnancy, you can get a very accurate result 10 days after ovulation. This is the method that clinical Chinese medicine physicians strongly recommend, because blood HCG is currently the most accurate way to detect early pregnancy and is widely favored in clinical medicine. The HCG blood test determines whether a woman is pregnant by accurately measuring the HCG level in her blood. Compared with traditional urine HCG, blood HCG is more accurate and has a smaller deviation. It can tell whether you are pregnant earlier, and the test time can be advanced to 10 days after intercourse, so it can accurately check whether you are pregnant.

Of course, it should be noted that B-ultrasound examination in the early stage of pregnancy cannot be detected too early, because the gestational sac has not formed at that time, so B-ultrasound examination can usually only make a diagnosis around 5 weeks of pregnancy. When the baby is 5 weeks pregnant in the uterus, a normal B-ultrasound can show the fetal heartbeat. The 3-8 weeks that the fetus is in the uterine cavity coincides with the division of human organs, which is a critical period for the division of human organs. Unnecessary external stimulation should be reduced.
