Abstract Hepatitis C virus (HCV) infection can have serious consequences when untreated and diagnosis is the first step in any treatment regimen. In the Unites States a 2-step algorithm consisting of HCV antibody screening and HCV RNA testing of HCV antibody-reactive specimens is recommended for detection of current HCV infection. We conducted a survey of HCV diagnostic practices in US public health laboratories and convened a meeting of HCV subject matter experts to identify opportunities for improvement in HCV diagnosis. Automatic reflexive HCV RNA testing of HCV antibody-reactive specimens was identified as a gap in laboratory practice. Only 54% of respondent laboratories always automatically reflexed or referred an anti-HCV-reactive specimen to an HCV RNA test. To facilitate diagnosis and ensure patients are not lost to follow-up, laboratories should ensure that the entire HCV testing algorithm can be completed with a sample(s) collected during a single patient visit.
