Rapid Flu Antigen Test

Illinois rates for HCPCS 87804

This is a rapid test that checks a nasal or throat sample directly for proteins from the influenza virus, with the result read visually rather than through a lab instrument. It gives a quick answer, typically within minutes, which helps guide same-visit treatment decisions. It is generally less sensitive than laboratory-based molecular testing, so a negative result does not always rule out infection.
