Profile Information

Test ID Reporting Name Available Separately Always Performed
HAIGM Hepatitis A IgM Ab, S Yes Yes
HBAG HBs Antigen, S Yes Yes
HBIM HBc IgM Ab, S Yes Yes
HCVDX HCV Ab w/Reflex to HCV PCR, S Yes Yes

Testing Algorithm

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

 

If the hepatitis B surface antigen result is reactive, then confirmation will be performed at an additional charge.

 

The following algorithms are available:
