There are two early pregnancy

Many female friends find that their menstrual period, which was originally very regular, has suddenly been delayed for more than ten days. Because they have had sexual intercourse recently, they suspect that they are pregnant. After such a situation occurs, female friends can use early pregnancy test paper to check. When testing, be sure to read the instruction manual carefully to avoid mismeasurement. So what is the matter with the two lines of the early pregnancy test paper after being left for a long time?

Early pregnancy test strips are common products on the market for women to self-test their pregnancy. They mainly determine whether a woman is pregnant by testing human chorionic gonadotropin. When using it, you should collect urine first, and then pour the urine into the test hole on the pregnancy test paper. If a line appears on the opposite side of the pregnancy test paper, it means that the test result is negative, indicating that the female friend is not pregnant. If obvious stains are observed in the test area, it means the test result is positive, indicating that the woman is pregnant. Some friends found that when the test was just finished, the result was negative, showing an obvious ink cartridge. Until after a while, it turned into two printer cartridges. The early pregnancy test paper should observe the test results within 5 to 10 minutes. If it is left for too long, the result will not be accurate.

What conditions can cause false positives?

1. On-site sampling. Human chorionic gonadotropin can usually only be detected a few days after a woman's embryo implants, so if the sample is taken too early, the test result will be inaccurate.

2. Symptom elements. If a woman suffers from hydatidiform mole, bronchial cancer, kidney cancer and other diseases, human chorionic gonadotropin will also be secreted, resulting in false detection.

3. Use expired pregnancy test paper. If the pregnancy test paper is still used after it expires, the test result will be inaccurate.

After female friends use the early pregnancy test paper to test, if the result is positive, they should see a doctor for urine test, B-ultrasound and other examinations. If the test result is negative and the woman still has not had her menstruation after a week, she should take another pregnancy test or go to the hospital for a check-up immediately. The early pregnancy test strip needs to be loaded at the required time, otherwise the test result will be inaccurate.
