Blood Antibody Test For A Specific Organism

Illinois rates for HCPCS 86784

This blood test looks for antibodies your immune system produced in response to a particular infectious organism. A positive result generally means you have been exposed to or infected by that organism at some point, while further testing sometimes distinguishes a recent infection from a past one. It is typically ordered when a specific infection is suspected based on symptoms or exposure history.
