Thank you doctor for the reply,
How soon can clinicians rule out infection? As per the study, laboratory testing using antigen or antibody detects HIV infection sooner than other available tests that detect only antibodies. Suppose a person gets a laboratory-based antigen or antibody test 45 days after a possible HIV exposure, and the result is negative. In that case, follow-up testing can begin 45 days after the possible exposure. If somehow the message therapist wants to infect me with a needle in her pocket, can I conclude that I am HIV-free irrespective of the risk at the time of exposure?
