What does it mean when two red lines appear on a pregnancy test stick?

Nowadays, many girls who want to know whether they are pregnant will go to the pharmacy to buy pregnancy test sticks, because pregnancy test sticks are simple, convenient and fast. However, women may feel confused when using the test stick, as the results of the pregnancy test stick are unclear despite the instructions. Some women are puzzled by the result of two red lines appearing on a pregnancy test. Below, the editor will explain the pregnancy test stick in detail for everyone.

The principle of pregnancy test stick is to determine whether a woman is pregnant by checking the HCG content in her urine. HCG is the abbreviation of human chorionic gonadotropin. If the sperm and egg combine and successfully implant in the uterus, the HCG content in the woman's urine will increase.

Pregnancy test stick "two bars"

Interpretation 1: Generally speaking, when the pregnancy test stick is tested, two red lines appear at the same time, that is, both the control line and the test line are displayed with purple-red lines, and the lines in the test area are very obvious, which indicates that there is a high possibility of pregnancy.

Interpretation 2: There will be two red lines in the following situations, but it is not actually pregnancy:

1. Signs of disease: In addition to the influence of HCG due to pregnancy, the "two bars" on the pregnancy test stick may also be caused by certain tumors such as choriocarcinoma, bronchial cancer, kidney cancer, and hydatidiform mole, which can also secrete HCG. In addition, clinically, there are cases where patients with endometrial hyperplasia have positive HCG test results. Therefore, the fact that the pregnancy test stick shows "two bars" does not mean that you are 100% sure that you are pregnant. Instead, you need to go to the hospital for a more detailed examination to rule out the possibility of disease.

2. If the pregnancy test stick is expired or improperly stored and becomes damp, the result may be a false positive, which may appear as "two bars".

Now everyone has an understanding of what it means to have two lines on a pregnancy test stick, and many women believe in the results of the pregnancy test stick. However, pregnancy test sticks can also "fail" sometimes. If the pregnancy test stick is expired or improperly stored and gets damp, the results will be biased. Therefore, the test results can often only be used as a reference. If you want further confirmation, it is best to go to the hospital for examination.
