Hepatitis C Reflex Testing

To ensure complete and timely diagnosis of HCV, HCV reflex testing is recommended following a reactive hepatitis C antibody screening test. Reflex testing means the laboratory will perform the hepatitis C antibody test, and if the result is positive, the laboratory will immediately perform an HCV RNA test on the same specimen. If the subsequent HCV RNA test is negative, HCV infection is effectively ruled out for most patients. If the reflex HCV RNA test is positive, a diagnosis of active HCV infection has been confirmed, and the individual should be referred directly for HCV care and treatment.

Reflex testing obviates the need for the patient to return for follow-up testing should the initially HCV antibody test be reactive. If the RNA test is negative, the work-up is done, and the patient may be reassured.
