Welcome to HCM!
antibody tests, if you get a non reactive test that is negative result after 3 months of your most recent possible exposure, you dont need to get tested again .
Follow-up diagnostic testing is performed if the first immunoassay
result is positive. Follow-up tests include; an antibody differentiation test, which distinguishes HIV-1 from HIV-2; an HIV-1 nucleic acid test
, which looks for virus directly, or the Western blot or indirect immunofluorescence assay, which detect antibodies
tests detect the virus directly (instead of the antibodies to HIV) and thus can detect HIV at about 10 days after infection—as soon as it appears in the bloodstream, before antibodies develop. If you are too anxious you can go for this test but you are not having HIV you dont need to be tested.
hope your query is answered.
