What is the reason for two lines on the pregnancy test stick?

For the sake of convenience, many women like to use pregnancy test sticks to test whether they are pregnant. In fact, there are times when pregnancy test sticks can fail to work. In many cases, two bars on the pregnancy test stick do not necessarily mean pregnancy. So what is the matter with two bars on the pregnancy test stick? Let us learn about this knowledge through the following article!

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.

There will be two red lines in the following cases, 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".

Experts say that the results of pregnancy test sticks can only be used as a reference. If you want further confirmation, it is best to go to the hospital for examination. Because there are many factors that affect the results of a pregnancy test. For example, within 7 days after a woman's ovulation period, the HCG hormone level in her body is relatively low, and it is easy to detect a false negative using a pregnancy test stick. In addition, if the menstruation is delayed for more than 7 days, or if there are menstrual irregularities, endocrine disorders, etc., the pregnancy test result may be positive. You can go to the hospital for a blood test, and the result may also be negative. In short, the test results of pregnancy test sticks can only be used as a reference.

It should be noted that some women, after finding a positive result in a pregnancy test, believe that it is a normal pregnancy and do not ask the hospital for confirmation. It was not until 6-8 weeks later when she experienced abnormal vaginal bleeding and lower abdominal pain that she rushed to the hospital for treatment. Little do people know that pregnancy test sticks cannot detect ectopic pregnancy or hydatidiform mole. If these two situations occur and are not discovered and treated in time, the consequences will be serious and may even be life-threatening.

The above is an introduction to the appearance of two bars on the pregnancy test stick. After reading the above article, do you have a more thorough understanding of this knowledge? For the accuracy of the results, I also recommend that patients go to the hospital for an ultrasonic test immediately after the pregnancy test stick shows two bars. Only in this way can you ensure that you are pregnant.
