If you have been tested for HIV infection, you may be told that the result is ‘non-reactive’.

This means that the test did not find any evidence of HIV infection.

You can be confident that you don’t have HIV and that you are HIV negative, so long as you have not been exposed to HIV quite recently, during the test’s window period. HIV diagnostic tests may miss infections that have been acquired in the month before testing.
