A laboratory test for HIV with a p24 antigen test performed 21 days after a potentially dangerous situation may not be fully reliable. Although IV-generation tests can detect infection earlier, a reliable negative result is recommended at least 12 weeks after exposure due to the so-called serological window period. Therefore, to be sure, I encourage you to repeat the test 3 months after the risky situation.
If you have any further doubts, it is worth consulting your attending physician. If you are unable to consult your doctor, you can use the teleconsultation here:
