How to read a pregnancy test stick
Disease description:
When I had intercourse with my boyfriend, we did not use any contraceptive measures. I would like to use a pregnancy test strip to check whether I am pregnant. I would like to ask the doctor, how to properly interpret the results of a pregnancy test strip?

Dr. Zhao Xiaodong
Pregnancy test strips primarily determine the result by observing the display window on the test strip. Interpretation of pregnancy test results is as follows:
1. **Positive:** If two red lines appear in the display window—that is, both the control line and the test line are visible, and the test area is clearly distinct—it indicates pregnancy.
2. **Negative:** If only one red control line appears and no test line is visible, it indicates no pregnancy.
3. **Weakly Positive:** If the test line appears lighter in color than the control line, it suggests a possible pregnancy. It is recommended to repeat the test or consult a healthcare provider for confirmation.
4. **Invalid:** If no red line appears on the test strip, or only the test line appears without the control line, it may indicate incorrect usage or a faulty test strip, rendering the result invalid.
To ensure accuracy, it is recommended to follow the instructions carefully and read the result within the specified time frame.
