a
RIBA 3 results were reported as positive when at least two antibodies were found and indeterminate when a single antibody was present (when antibodies were absent, samples were declared negative).
b
PA 1:400 indicates serum dilution at 1:400 in the particle agglutination assay.
c
This sample was also positive by the IMUCHECK-HCV enzyme-linked immunosorbent assay.
