Ive been reading up about the 4th gen test though. It search for both antibodies and the p24 antigens. Usually its 3 situations if the p24 antigens cannot be picked up by the test. 1) You're hiv negative 2) you've been infected 4-6 weeks earlier 3) p24 antigens to low for current tech to pickup. According to paid doctors (yes i paid for doctor subscriptions) and medical journals the p24 antigen protein starts to show in the blood at 14-16 days, and peaks at 28 days post exposure. So a negative at 28 days is pretty much 95% but cdc recommends 3 months for it to be fully conclusive. |

Usually test are designed to be more false positive. Usually false negative quite rare unless the test kit totally cock up. Once negative, usually quite conclusive
