WebDetection of borderline and/or low positive anti-HCV results by enzyme immunoassay (EIA) leads to severe problems in routine laboratories and needs confirmation with nucleic acid amplification tests which can increase the cost. In EIA tests, if the ratio of sample to cut-off (S/Co) is ≥ 1, the sampl … WebSera from blood donors were analyzed by Enzyme-Linked Immunosorbent Assay (ELISA) and RT-PCR assay to detect HCV infection. Results: The samples were divided into two groups based on their serological results: group A--S/CO ratio < 3 (60 samples) and group B--S/CO ratio > 3 (41 samples).
