Is Geenius HCV Supplemental Assay an Alternative to HCV Confirmatory Western Blot INNO‐LIA HCV Score in Repeatedly Reactive Blood Donations After First Line Screening?

Journal of Clinical Laboratory Analysis, EarlyView.
Serological testing of low prevalent blood donors: serological windows and false‐reactive screening results. There is moderate agreement between rapid immunochromatography test and western blot detecting anti‐HCV antibodies in blood donor sera. Discrepancies in results of immunochromatography test and western blot detecting anti‐HCV antibodies occur in
