Picture of pregnancy test paper

When we check whether we are pregnant, we usually do self-diagnosis first. The second way to diagnose is by using early pregnancy test paper. The result of early pregnancy test paper can only be used as a reference and cannot be completely relied on. Do you know the reason why the early pregnancy test paper shows weak positive result when not pregnant? Let's take this doubt and follow the editor to look at the standard answer to the question.

What are the photos of not pregnant and pregnancy test strips?

If the test paper shows two bars, it means you are pregnant. If it shows only one bar, it means you are not pregnant or the pregnancy time is too short. The temporary test paper cannot detect it. If your menstruation is delayed, you can test the blood HCG first.

The reason why the early pregnancy test paper is weak positive when you are not pregnant

If the early pregnancy test paper is weakly positive but you go to the hospital for further testing and find that you are not pregnant, it may be that you used the early pregnancy test paper too early. Generally speaking, the combination of sperm and egg can only be detected after HCG, that is, human chorionic gonadotropin, reaches a certain amount a few days later, and then an accurate result can be obtained. Generally, the test can only be done when the woman's menstrual period is delayed. In this way, a positive early pregnancy test may mean pregnancy, but the final result still needs to be based on the result of a physical examination in the hospital.

A weak positive result on an early pregnancy test may also indicate that you are not pregnant. Weak positive results on early pregnancy tests before menstruation are common in clinical medicine. If you are worried, generally wait for about 5 days after the menstrual period, and test the first urine in the morning with a test strip. If the early pregnancy test strip is still weakly positive at this time, the possibility of pregnancy is 90%. If you are still worried at this time, you can go to the hospital for B-ultrasound examination and diagnosis. A weak positive result on an early pregnancy test does not mean 100% pregnancy. Some tumor cells, such as hydatidiform mole, choriocarcinoma, bronchial carcinoma and renal carcinoma, can also metabolize hCG. If the early pregnancy test paper always shows weak positive results, it may be caused by incorrect operation of the early pregnancy test paper. If the operation is confirmed to be correct, but the result of the early pregnancy test paper is weak positive, it may be that the pregnancy has just begun and the hCG level in the body is generally low. It is best to leave the sample to be tested still for more than 3 minutes, and be sure to carefully distinguish whether it is a weak positive. Many types of early pregnancy test strips indicate that women can take a pregnancy test one day after missing their normal menstrual period. In fact, the rate and amount of hCG secretion in the body is not necessarily the same for pregnant women, which varies from person to person. If you have to do a urine test, the results you get may be inaccurate. Therefore, it is best to take a pregnancy test two weeks after your period is delayed, so that the result will be more reliable.

Are early pregnancy test strips accurate?

Although early pregnancy test strips are said to be 99% accurate, you should never trust the test results too much. According to surveys, the accuracy of early pregnancy test strips varies greatly, ranging from 50% to 98%. If the test result is negative and your period still occurs a week later, you should do another test. If it still shows negative, it is best to see a doctor and trust your body. If you have many symptoms of pregnancy, no matter what the test results are, you should remember that the principle of early pregnancy test strips is only a basic test. There will be errors in the use of early pregnancy test strips. Therefore, the best way at this time is to go to the hospital for HCG blood test, HCG urine test and B-ultrasound examination.

This type of testing method has the advantages of being rapid, convenient, flexible and highly specific, but don't take chances. When using early pregnancy test strips, pay attention to some unexpected situations, otherwise there may be a false negative or positive result. For example: pay attention to the production time on the gift box, do not use expired early pregnancy test strips; read the instructions carefully before doing the test, and then carefully follow the instructions; the results of the test with morning urine will be more accurate, etc. Many early pregnancy test strips indicate that women can do an early pregnancy test 1-2 days after missing their normal menstrual period.
