Testing Algorithm

If hepatitis C virus (HCV) antibody is reactive, then HCV RNA detection and quantification by real-time reverse transcription polymerase chain reaction will be performed at an additional charge.

 

If hepatitis B virus surface antigen (HBsAg) is reactive, then confirmation will be performed at an additional charge.
