If the PEP has worked, or the person was not initially infected, this will show as a negative HIV test at one month and three months after the PEP treatment finishes. If the PEP has not worked, this will be shown in a positive test result. Testing 4 weeks after PEP will detect 95% of infections. Testing three months after PEP will detect more than 99.99% of infections and is considered confirmation that someone is HIV negative. If PEP has not worked, seroconversion usually occurs 1-3 weeks after PEP is finished, although only 80% of people show these symptoms.
