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.
The following algorithms are available:
-Chronic Hepatitis C Treatment and Monitoring Algorithm: Direct Antiviral Antigen (DAA) Combination
-Hepatitis B: Testing Algorithm for Screening, Diagnosis, and Management
