Is a negative HIV test four weeks after PEP okay?
Is it possible to test positive after testing negative after completing 28 day of PEP?
In the UK, people need to wait 4 weeks after the last dose of PEP before taking an HIV test.
If this test is negative, then someone is told they do not have HIV.
There is no point taking an HIV test as soon as you finish PEP though. This is because the PEP could just be covering up or delaying a potential infection.
