Basically in most cases of HIV, detectable antibodies are developed within 2 to 8 weeks (the average is 25 days).
If it is Alere Determine HIV-1/2 Ag/Ab Combo test that detects both HIV-1/2 antibodies and the HIV-1 p24 antigen, which can appear just 12-26 days after infection.
HIV-1/2 antibodies first appear significantly later – 20 to 45 days after infection.
The rapid tests for HIV antibodies are very accurate with a sensitivity and specificity of 99.6 - 99.9%.
However it's good to have retest after 3 months also to get 100% conclusive.
