Comments:
Confirmatory testing by RIBA is only recommended when the EIA screen is ‘weakly positive’ (i.e., S/CO <3.0). RIBA results are reported as positive or negative in this assay. Patients with positive HCV antibodies by EIA should be evaluated with a sensitive qualitative nucleic acid test for HCV RNA (Hepatitis C Virus RNA DetectR) to rule out active infection.
