Hepatitis C RNA Reflex Tests Now Available from Commercial Labs

RNA testing is needed to confirm current hepatitis C infection in patients who test positive for hepatitis C antibody. Too often, though, the RNA test is not ordered after a positive antibody test. Now, clinicians can now order a hepatitis C reflex test from several commercial laboratories: the laboratory will do the hepatitis C antibody test, and if the result is positive, the laboratory will immediately do a quantitative RNA test on the same specimen. Only one tube of serum is needed. This reflex test provides the information needed to determine hepatitis C infection status in one step, without having the patient return for a second blood draw.
