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. An antibody test at 4 weeks will detect 95% of infections.

For most people who are infected, the anti-HCV blood test will become positive by 6 months after exposure.
