It's conclusive.: The p24 antigen is a viral core protein that appears in the blood as the viral RNA level rises following HIV infection. The test turns (+) 5-7 days after viral RNA appears in the blood. It is 89-100% as sensitive as viral RNA.This assay detects a level of antigen that approximately corresponds to an HIV RNA level of 30,000 to 50,000 copies/mL .
