A test that only sees the antigen as empty

Hello, I took an antigen test 21 days after the dangerous relationship.  The antigen is called p24.  Is the answer definitive?  I tested after 21 days.  Is it enough?  Should I retest?  The doctor said give it after six months, do I need to do the test again??  Or is this test that I gave a definitive answer enough?  Do not worry?  thank you for your answer

What was your risk?

An antigen-only test is NOT the correct test for that time period. You should take an Ag/Ab test at least 28 days after your event, assuming you actually had an HIV risk.

i have a vaginal sex with my boy friend hesaid me he had a sex 4 years ago and I took him for a test, it was negative, but I was stressed because when he had sex with me, he had sex with someone else at the same time, that's why it's been 21 days since our last sex, and I took a test today, is it enough?  Or should I test again?  I asked a consultant and he said that on the 21st day, three weeks have passed, give him a test because this test only sees the ag, is the answer enough?
The advice was clear. It should not need to be repeated.> "An antigen-only test is NOT the correct test for that time period. You should take an Ag/Ab test at least 28 days after your event"
