How many lines on the pregnancy test stick indicate pregnancy

With the development of medical technology in modern society, if a woman wants to guess whether she is pregnant, she can not only go to the hospital for a blood test, but also go to the pharmacy to buy pregnancy test sticks and pregnancy test paper to confirm whether she is pregnant. Although pregnancy test sticks do not cause bleeding and the results presented by the test are not as accurate and intuitive, pregnancy test sticks also provide great convenience for women. When using a pregnancy test stick, how many lines on it indicate pregnancy?

How many lines on the pregnancy test stick indicate pregnancy

After pregnancy, human chorionic gonadotropin (HCG) is produced in the pregnant woman's body, which helps maintain the pregnancy. Pregnancy test sticks are determined by measuring HCG in urine. So, how do you read a pregnancy test stick?

How to check pregnancy with pregnancy test stick? Pregnancy test sticks generally have the following judgment results:

1. There are two red lines on the pregnancy test stick: one is located in the test area (T) and the other is in the quality control area (C). It is a positive result, indicating pregnancy.

2. A red line on the pregnancy test stick: Only a purple-red strip appears in the quality control area (C), and no purple-red strip appears in the test area (T). A negative result indicates that you are not pregnant.

3. One line on the pregnancy test stick is dark and the other is light: one line is in the test area (T) and is relatively light, while the other line is in the quality control area (C) and is darker. This is a weak positive result, indicating the possibility of pregnancy.

4. There is no red line on the pregnancy test stick: No purple-red strip appears in the quality control area (C), indicating an incorrect operation process or the reagent strip has deteriorated and damaged.

The results of pregnancy test sticks after pregnancy are not 100% accurate. If you want to confirm whether you are pregnant, it is recommended to go to a local hospital for blood tests, B-ultrasound and other auxiliary examinations to confirm. When looking at a pregnancy test stick, you must clearly identify the control line and the test line. If the control line does not appear, it means that the test is invalid or has failed.

1. Not pregnant: Only one control line appears, indicating no pregnancy.

2. Pregnancy: If two lines appear, that is, both the control line and the test line are colored, and the test line is obviously clear, it means that you are pregnant; if the control line is obviously clear and the test line is very light, it means that you may be pregnant. Please collect morning urine with a new morning paper and retest every 2 days.

3. Invalid: No control line appears within 5 minutes, indicating that the test is invalid or failed.

It should be noted that when the pregnancy test stick shows "two bars", do not assume that you are pregnant and stop doing further tests. Because "two bars" does not necessarily mean pregnancy. In addition to the human chorionic gonadotropin in urine that can cause two bars to appear on the pregnancy test stick, certain tumor cells or hydatidiform mole in a woman's body may also cause "two bars" to appear on the pregnancy test stick.
