Re: P24 Antigen test - too soon?
Yes it is accurate (very) but not conclusive. You will have to have result confirmed at 12 weeks. It is very unlikely to change.
Here is a statement for BASHH (British Association for Sexual Health and HIV) dated 2010.
"Patients attending for HIV testing who identify a specific risk occurring more that 4 weeks previously, should not be made to wait 3 months (12 weeks) before HIV testing. They should be offered a 4th generation laboratory HIV test and advised that a negative result at 4 weeks post exposure is very reassuring/highly likely to exclude HIV infection. An additional HIV test should be offered to all persons at 3 months (12 weeks) to definitively exclude HIV infection. Patients at lower risk may opt to wait until 3 months to avoid the need for HIV testing twice."
