0.9 positive: > 0.9 the cdc recommends that a positive hcv antibody result be followed up with a hcv nucleic acid amplification test what is this?

A doctor has provided 1 answer

HCV confirmation: Both HCV antibody test and HCV nucleic acid amplification test (also called HCV RNA by PCR) are blood tests for diagnosing Hepatitis C. HCV antibody is a screening test - it detects the presence of a protein (antibody) that our system has developed against Hepatitis C virus. HCV RNA by PCR test measures directly the presence of Hepatitis C virus in the blood and is a confirmatory test for HCV.
