Is 8 Weeks enough for HIV test?
The first HIV protein (antigen) that can be measured is p24 (from 1 to 8 weeks after exposure). Viral load and p24 tests are not accurate for diagnosing early HIV if the results are negative. An HIV antibody response can be detected as early as two weeks in a few people and in more than 99.9% of people by 12 weeks.
How accurate is a 4th generation HIV test after 8 weeks?
Yes. Modern HIV tests are very accurate. For example, 4th generation tests will pick up 99% of infections at six week. Testing earlier, for example after four week, only detects 95% of infections. Testing earlier needs a confirmatory test three months after the risk.
Is a negative HIV test at 10 weeks conclusive?
It depends which test you use. 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.
Is a negative rapid HIV test at 6 weeks conclusive?
Evidence suggests that a test taken 6 weeks after your last risk is accurate for more than 90% of the population. Although testing after 6 weeks but before 12 weeks may give you a good indication as to your HIV status, we still recommend that you retest at 12 weeks for a 100% accurate negative test result.
Is a negative HIV test 8 weeks post exposure good?
