PEP taken for only 10 days and then stopped does not fully suppress the virus â it may slow viral replication but not clear it. Because of this, the window period can get shifted by a few days. A standard 4th gen test (which detects p24 antigen + antibodies) done at 21 days while on incomplete PEP may not be conclusive. It is generally recommended to retest at 45 days after your last exposure or last PEP dose for a reliable result.

Taking PEP for only 10 days may suppress viral replication temporarily, so a 21-day p24 antigen test is not considered fully conclusive. PEP can delay detectability in some cases. Usually, HIV 4th generation (p24 + antibody) testing is recommended at 6 weeks after stopping PEP, and a final test at 3 months after stopping PEP for confirmation. A negative 21-day result is reassuring, but repeat testing at the recommended interval is advised.
