How long after a possible HIV exposure should I do at home testing. (I want the results to be reliable.)?

Not the best test: The home self test for HIV takes up to 3 months to give reliable results, the longest of all HIV tests. It is never the best test to check for infection after a particular exposure. Better to go to a doctor or clinic and have an HIV antigen/antibody test ("4th generation" or "duo" test), which is reliable after only 4 weeks. You also need testing for STDs, for which you are at much higher risk. ...Read more

Too soon to test: You could have taken prophylactic treatment within a day or so of the exposure. However, testing one week after exposure will not be meaningful. if the result is negative it would not rule out HIV infection. The fastest and most specific way to diagnose would be to get a HIV nucleic acid test after 3 months, if the antibody test is negative at that time. ...Read more
