Dear Lybrate user. 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. Take care.
