How to read HIV test results?
How an HIV self-test result is read depends on the specific test you use. Always read the result at the time stated in the Instructions for Use supplied with the test and do not interpret it outside the specified reading time.
For many rapid HIV self-tests that use control (C) and test (T) indicators, results are interpreted as follows:
- Non-reactive result: the required control indicator is visible and no test indicator is present. A non-reactive result does not completely exclude HIV infection if testing was performed during the applicable window period or after a recent possible exposure.
- Reactive result: the required control indicator and a test indicator are visible. The appearance of the test indicator can vary between products, so always follow the interpretation instructions supplied with your specific test. A reactive HIV self-test result does not by itself confirm an HIV diagnosis and requires appropriate follow-up testing.
- Invalid result: the required control indicator does not appear. Do not interpret an invalid result. Repeat the test using a new device and follow the Instructions for Use carefully.
If you are unsure how to perform or interpret your test, see our HIV test step-by-step guides.
If you recently had a possible exposure, also see When to test for HIV? for more information about HIV test window periods.
