HBGNTHBs Antigen Confirmation, SNoNo
HCVQNHCV RNA Detect/Quant, SYesNo

Testing Algorithm Delineates situations when tests are added to the initial order. This includes reflex and additional tests.

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.
