Experience Sharing: Hepatitis C Virus Reflex Testing

A thorough HCV care cascade involves proper screening, confirmation of the presence of HCV RNA, and linking patients to medical care. The multistep testing procedure represents barriers to HCV care. HCV reflex testing is a strategy that simplifies the diagnostic algorithms. Namely, the laboratory performs anti-HCV testing first, if the result is positive, the laboratory will immediately perform an HCV RNA test on the same blood sample. Reflex testing obviates the need for the patient to return for follow-up testing should the initially HCV antibody test be reactive. Implementation of reflex testing enables timely and accurate diagnosis of HCV.

Traditional Testing vs HCV Reflex Testing
Reflex Testing: R.N.A model (+)

The in-hospital hepatitis C care cascade (R.N.A model) includes serial modalities: (1) HCV reflex testing (increasing timely and accurate diagnosis) (2) Real-time automatic appointments (enhancing accessibility), and (3) Late call-back for the missing patients (raising awareness).

Implementation of R.N.A model is associated with a significant increase in HCV RNA diagnosis and treatment rate for patients from non-hepatology departments. This care cascade successfully increased the treatment update and set up a model for enhancing in-hospital HCV elimination.
