My test has a line at the “C” and a very dark line at the “T”. What does it mean?

If your test result shows a line next to the letter “C” and a line next to the letter “T”, your test is reactive. This result shows that there is a possibility that you may be infected with HIV. However, the intensity of the lines on the test key does not correspond to the stage of the disease or the potential for infection.

You will need a second test to confirm your result. Until your test result is confirmed, please take precautions to avoid the risk of spreading HIV.
