ELISA and Hepatitis C Polymerase Chain Reaction (PCR) are tests used to detect antibodies (ELISA) and viral RNA (PCR), respectively. Most physicians will screen blood samples of at-risk patients for antibodies to HCV. If reactive, the sample is then tested by PCR, both qualitative (is HCV RNA present in the sample) and quantitative (how much virus is present).
