Correlation between the S/Co values and golden standards of HCV diagnosis. No significant correlations were observed between the S/Co values of sera assessed against denatured antigens and other clinical parameters, while those obtained from the soluble antigen-based immunoassay showed positive correlations with viral load, liver transaminases as well as total bilirubin levels in chronic/treatment-naïve patients A-D, and were inversely correlated with the viral load in relapse /treatment-failure sera (E). When tested in the whole viremic group, the S/Co values were positively correlated with both viral load (F) and ALT levels (G)
