Pregnancy Test Stick Usage and Interpretation

The pregnancy test stick is a relatively simple method to detect pregnancy, which is popular among women preparing for pregnancy due to its ease of use. It allows for self-testing at home, without the need to visit a hospital, and it typically has a high accuracy rate. However, it is important to be aware of the precautions when using a pregnancy test stick to avoid inaccurate results due to improper use. Below is a guide on how to interpret the results of a pregnancy test stick.

1. How to Interpret the Results of a Pregnancy Test Stick

a. Not Pregnant: Only one control line appears, indicating that the woman is not pregnant.

b. Pregnant: Two lines appear, both the control line and the test line are visible, and the test line is clearly distinct, indicating pregnancy. If the control line is clearly visible but the test line is faintly colored, it may indicate a possible pregnancy. In this case, it is recommended to repeat the test with a new test stick in two days using morning urine.

c. Invalid: If no control line appears within 5 minutes, it means the test is invalid or failed.

It is worth noting that a positive result on the pregnancy test stick does not necessarily mean that the woman is definitely pregnant. In addition to pregnancy, certain tumor cells or molar pregnancy in the woman's body may also cause the pregnancy test stick to display two lines.

2. General Interpretation of Pregnancy Test Stick Results

a. Two Red Lines on the Pregnancy Test Stick: One line is located in the test area (T), and the other is in the control area (C). This is a positive result, indicating pregnancy.

b. One Red Line on the Pregnancy Test Stick: Only one purple-red band appears in the control area (C), and no purple-red band appears in the test area (T). This is a negative result, indicating that the woman is not pregnant.

c. One Dark and One Light Line on the Pregnancy Test Stick: One line is faintly colored in the test area (T), and the other line is darker in the control area (C). This is a weak positive result, indicating a possibility of pregnancy.

d. No Red Lines on the Pregnancy Test Stick: If no purple-red band appears in the control area (C), it indicates incorrect operation or that the test strip has deteriorated or been damaged.
