The only way to tell. The only way to tell if a person has HIV is through the HIV Antibody Test, which detects the presence of antibodies produced by the body in response to the HIV virus. It can take up to three months for antibodies to be developed.
These tests can find recent infection earlier than tests that detect only antibodies. These antigen/antibody combination tests can find HIV as soon as 3 weeks after exposure to the virus, but they are only available for testing blood, not oral fluid.
