ARUP intends use of this assay for clinical diagnosis. This assay should not be used for blood donor screening, associated re-entry protocols, or for screening Human Cell, Tissues and Cellular and Tissue-Based Products (HCT/P).

Note: If anti-HCV screen is low-positive, then anti-HCV recombinant immunoblot (RIBA) will be added. For high-positive anti-HCV screening results, ARUP recommends collecting a new specimen and testing for Hepatitis C RNA by PCR or bDNA.
CPT Code(s): 86803 HCVAB; if reflexed, add 86804 HCVAB RIBA
