What it is

This lab test checks blood for the HIV-1 p24 antigen and for antibodies to HIV-1 and HIV-2 at the same time. Because it detects the antigen, it can find an infection earlier than antibody-only tests and is the standard first test for HIV screening.

What the price covers

The price usually covers the screening test only. The blood draw is often billed separately, and a positive result needs a follow-up confirmation test with its own charge.
