False positive pregnancy test

As people age, their sexual and reproductive organs gradually develop fully, and a large amount of hormones and dopamine and other sex hormones are secreted in the human body. People begin to desire close contact with the opposite sex, and sex is one of the intimate activities for lovers to communicate their emotions. However, during sex, contraceptive measures must also be taken. When they suspect they are pregnant, many women will use early pregnancy test strips for testing. So what happens if the early pregnancy test strips show a false positive?

In general, using an early pregnancy test strip to test whether you are pregnant will detect two results: drop urine into the detection hole on the test strip. If a colored band appears in the control area of ​​the test strip (some test strips appear red, some test strips appear blue), it indicates a negative result, indicating that you are not pregnant; conversely, if a clear colored band appears in the detection area, it indicates a positive result, indicating that you are pregnant. Is it very quick and convenient to use an early pregnancy test strip? There is one situation that you should pay attention to. If the early pregnancy test strip shows one dark and one light color, it is clinically called a weak positive result. At this time, you should highly consider the possibility of pregnancy.

What is the reason for a weak positive result on the early pregnancy test paper ?

1. If the pregnancy has just begun or there is a possibility of ectopic pregnancy, the HCG level in the body is generally low. The test sample needs to be left to stand for more than 3 minutes, and you must carefully identify whether there is a weak positive on the early pregnancy test paper. The color band in the test area only appears faintly.

2. If the early pregnancy test paper is stored for too long (more than 1 year) or is not kept properly (such as being exposed to moisture), and is not kept at normal room temperature, it may become invalid and a false negative test result may occur.

3. After 3 months of pregnancy, the HCG level decreases, and the early pregnancy test sometimes shows a negative result, or a weak positive result; a positive result does not mean 100% pregnancy.

4. If the early pregnancy test paper is weakly positive, or women of childbearing age have amenorrhea or suspect pregnancy, do not rely solely on a single early pregnancy test to determine whether they are pregnant. To be on the safe side, you can test again after 3 days. Of course, the most reliable thing is to go to the hospital for a comprehensive examination in time, especially for those with weak positive results, so that measures can be taken as soon as possible.

5. Some tumor cells, such as hydatidiform mole, choriocarcinoma, bronchial carcinoma and renal cancer, can also secrete HCG. We have also encountered patients with endometrial hyperplasia who tested positive for HCG.

2. The pregnancy test paper shows a weak positive result. Is the baby pregnant?

I am really looking forward to the arrival of the baby, but I have been preparing for pregnancy for a long time. When I used the early pregnancy test paper, it turned out to be weak positive. I am so confused. Is this cute baby pregnant?

1. A weak positive result on an early pregnancy test cannot rule out the possibility of not being pregnant. A weak positive result on an early pregnancy test before menstruation has been seen many times in clinical practice. If you are worried, generally wait for about 5 days after your period, and then test with the test paper for the first urine. If the early pregnancy test paper still shows a weak positive result at this time, the possibility of pregnancy is 90%. If you are still worried at this time, you can go to the hospital for an ultrasound examination to confirm the diagnosis.

2. A weak positive result on an early pregnancy test does not mean 100% pregnancy. Because some tumor cells, such as hydatidiform mole, choriocarcinoma, bronchial carcinoma and renal cancer, can also secrete HCG.

3. If the early pregnancy test paper is always weakly positive, it may be caused by improper use of the early pregnancy test paper. If you confirm that your operation is correct, the early pregnancy test paper is weakly positive, it may be that the pregnancy has just begun, and the HCG level in the body is generally low. The test sample needs to be left standing for more than 3 minutes, and you must carefully identify whether there is a weak positive on the early pregnancy test paper. The color band in the detection area only appears faintly.

Although many types of early pregnancy test strips indicate that women can do a pregnancy self-test one day after missing their normal menstrual period, in fact, not all pregnant women secrete human chorionic gonadotropin (hCG) at the same rate and in the same amount. This varies from person to person. If you do a urine test too early, the results may be false. Therefore, it is best to do a pregnancy self-test two weeks after your period is late, so that the result will be more reliable.
