A stand alone P24 Ag test after 12 weeks post exposure is almost useless. Should you be trying to determine your sero-status after a potential exposure and you have crossed the time frame of 12 weeks from the time of your exposure a standard HIV antibody test is good enough.

For the WWs here in the forum -

The correct time to get a stand alone p24 AG test is 14-21 days post exposure. However, a negative at that time frame in no means indicates a conclusive result. A combo test / duo test (P24 AG + 3rd Gen AB test) at the 6th week is much adept and indicative at the aforesaid time frame. 12 week's conclusive.

Just a p24 is not conclusive, if done with an antibody test then conclusive. If not then get an antibody test done.
