Specimen Transport:

Transport specimen to the laboratory. Transport with coolant pack if coming from clinic location.



Reference Interval:  Nonreactive


Interpretive Guidelines:


Nonreactive:  The method detects the IgG antibodies to Hepatitis C virus. A negative test result does not exclude the possibility of exposure to HCV. There may be a delay in the production of antibodies to the virus. You may repeat the test in four to eight weeks to determine if antibodies have been produced.


Borderline:  CDC recommends confirmatory testing of borderline results.  Please place a new order for Hepatitis C RNA, Quant, PCR [XHCVRQ]


Reactive - Index value :

CDC recommends confirmatory testing of reactive results.  Please place a new order for Hepatitis C RNA, Quant, PCR [XHCVRQ] 


Test Limitations:

Results may be affected if patient has developed heterophilic antibodies due to exposure to animal based protein products.


The assay is an in vitro diagnostic immunoassay for qualitative determination of immunoglobulin G (IgG) antibodies to hepatitis C virus.


The assay performance characteristics have not been established for cadaver specimens, heat inactivated specimens and body fluids other than serum.

Additional Information:

This method is approved for diagnostic testing only.  It is not approved for screening tissue donors that fall under FDA's HCT/P requirements.
