Does the test paper showing one dark and one light indicates pregnancy?

Test paper is a product for detecting whether women are pregnant, but some test papers are not standardized and may cause differences in the test results. If the test paper is used in a standardized way, the accuracy of the test result will be much higher. So, does the phenomenon of one dark and one light on the test paper mean pregnancy? Let’s find out together.

What does it mean when the test paper shows one dark and one light?

1. Taking pregnancy test too early

Generally speaking, early pregnancy test strips should be used to successfully detect women 3 to 7 days after their menstruation. However, since most women who have their first menstruation are afraid of getting pregnant, they rush to test within 1 to 2 days of their menstruation, resulting in inaccurate HCG detection or a dark and light HCG result. It is recommended to test again the next day or wait longer after the menstruation.

2. Urine concentration is too low

Early pregnancy test strips should be tested in the first urine in the morning as much as possible, because female hormones at this time are most easily detected. If there is really no urine in the morning or if you drank too much water last night, you must at least ensure that the urine is in the bladder for at least four hours before testing. Otherwise, it is easy to cause the pregnancy test paper to be dark and light.

3. Influence of drugs or diseases

Because the main hormone HCG for pregnancy testing will not only increase in level after unexpected pregnancy, but also increase due to some diseases, such as ovarian tumors, uterine cancer, stomach cancer, liver cancer, etc., resulting in the phenomenon of one dark and one shallow, so women should go to a professional hospital for reconfirmation when the test result is one dark and one shallow after menopause. If the test result is one deep and one shallow due to illness rather than pregnancy, then you need to seek medical attention immediately.

Many women use early pregnancy test strips to do the most basic pregnancy test, but if the operation is incorrect or the purchase is unscientific, it will affect the normal test results. Therefore, when using pregnancy test strips, you must pay attention to the following common problems in the use of pregnancy test strips.

Common questions about early pregnancy papers:

1. If the pregnancy test paper you buy is stored for too long (more than 1 year), or if the pregnancy test paper is damp and not stored at normal room temperature (not refrigerated), it may become invalid and result in a false negative test result. Therefore, pay attention to the production time when purchasing.

2. If pregnancy has just begun, or there is a possibility of ectopic pregnancy, the body's HCG level is generally slightly low. The test sample needs to be left alone for more than 3 minutes (usually only 1 minute), and careful identification must be made to see if there is a weak positive - the printed color band in the test area only appears faintly.

3. After three months of pregnancy, HCG levels decrease and urine tests may sometimes show negative or weak positive results.

4. In extreme cases, such as hydatidiform mole and choriocarcinoma, the body's HCG level will be too high and the urine test may not show a positive result.

Based on the above content, we can understand that many women will use test paper to check whether they are pregnant. At the same time, due to incorrect use, the test paper will cause many problems, including one deep and one shallow. Therefore, if you want a completely accurate result, women still need to go to the hospital for a check-up.
