Aug 21, 2008 ยท Yesterday i took a oraquick test, which was 6 weeks and 3 days since possible exposure, and it came out negative. i am still very anxious and i plan to get another test in a couple of weeks Aug 5, 2023 ยท Repeat HIV testing will be obtained 30 days and 90 days after exposure. Testing should be performed using a fourth-generation HIV test. If a fourth-generation test is unavailable, an older test may be used along with more frequent follow-up appointments to limit the possibility of a false-negative result. This Better2Know HIV test is extremely accurate at 28 days and is now the test recommended by the UK's current Guidelines on HIV testing. The Better2Know test is a fourth generation test, considered 99.8% accurate at 28 days. This accuracy increases to 99.9% at 90 days, after any potential contact. Dec 20, 2010 ยท A fourth generation test will detect 95% of infections 28 days after a possible exposure. This needs to be confirmed by a second test 90 days after the exposure. A third generation test (antibody only) test is accurate 6-12 weeks after a possible exposure. For more information please follow this link. Lisa Thorley โ€ข 23 December 2016. Hi Michael, This technique has evolved from the first-generation viral lysate-based immunoglobulin G (IgG) tests, to the second-generation tests incorporating recombinant and/or synthetic peptide antigens, to the third-generation tests which detect IgG and IgM (antigen sandwich techniques), and finally to the third-generation-plus assays which also detect Most healthcare professionals consider a 4th generation hiv test to be conclusive at around 6 weeks post-exposure. Some guidelines recommend confirming the result with a follow-up test at around 12 weeks (3 months) after exposure to ensure accuracy. .
