A member asked:
How accurate is the hiv antibody/antigen blood test at 8 weeks after exposure? conclusive?
A doctor has provided 1 answer
Test accuracy: Every test we do has a margin of error, due to both the nature of the test itself or how people behave when they collect samples, and the biologic variation between people. That said, the antibody tests for HIV perform quite well and in the setting of a suspect exposure are largely conclusive. However, the nucleic acid tests are far more specific than antibody-based tests can be.
