What is the normal value for hepatitis C antibody?

The normal reference range for hepatitis C virus (HCV) antibody is 0–1 U/L. A test result within this range is considered negative, generally indicating no HCV infection. A result greater than 1 U/L is considered positive, suggesting possible HCV infection; however, this is not definitive, as false-positive antibody results can occur. Further testing for HCV RNA is therefore required to confirm infection.

A positive HCV RNA test confirms a diagnosis of hepatitis C. Conversely, a negative HCV RNA test in the setting of an initially positive antibody screen suggests a false-positive antibody result. For patients diagnosed with hepatitis C, current standard treatment consists of antiviral therapy alone, with a treatment duration of only three months. This oral antiviral regimen is highly effective, achieving cure rates exceeding 99%.
