How accurate is a ab/ag hiv poc test between week 2 and 3 after exposure at detecting p24 antigen? ....(this is not a question about antibodies)

See below: A negative result will not exclude HIV infection. A positive result is reliable.

Not good enough: That test would detect 50-70% of new HIV infections 2-3 weeks after exposure. A nearly conclusive result is available at 4 weeks, and 100% at 6 weeks.
