What is it? This laboratory test measures the amount of hepatitis C viral RNA in a patient’s blood. Viral RNA (ribonucleic acid) is genetic material from the hepatitis C virus. This test is used with the Bayer System 340 bDNA Analyzer.
How does it work? In a laboratory, a sample of a patient’s blood is put into a tiny special container in a Bayer System 340 bDNA Analyzer. The Analyzer adds a series of chemicals that react with genetic material from the hepatitis C virus to ultimately produce light. The Analyzer measures the light, which shows how much hepatitis C viral RNA there was in the patient’s blood.
When is it used? A doctor uses this test two or more times while treating a patient with antiviral therapy to see if the patient has not responded to the anti-viral treatment.
What will it accomplish? This test will tell the doctor and patient if antiviral treatment has failed to help cure the patient of hepatitis C infection.
When should it not be used? The assay should not be used to determine if a person is infected with hepatitis C virus. It should not be used to screen blood or blood products for transfusion. And, it should not be used to predict whether an antiviral treatment will be successful.
