HelpTest Code HCCDD Hepatitis C Virus Antibody, Cadaveric or Hemolyzed Specimens, Symptomatic, Serum
Reporting Name
HCV Ab Cadaver/Hemolyzed, SPerforming Laboratory
Mayo Clinic Laboratories in Rochester
Useful For
Diagnosis of hepatitis C virus (HCV) infection in cadaveric or hemolyzed serum specimens from symptomatic patients with or without risk factors for HCV infection
This test is not intended for screening blood, cell, or tissue donors.
This test is not useful for ruling out acute HCV infections.
This test is not useful for differentiation between resolved and acute or chronic hepatitis C infections.
This test is not intended for testing asymptomatic individuals (ie, screening purposes).
Method Name
Enzyme Immunoassay (EIA)
Ordering Guidance
For testing hemolyzed specimens from asymptomatic patients with or without risk factors for hepatitis C virus infection, order HCCAD / Hepatitis C Virus Antibody Screen, Cadaveric or Hemolyzed Specimens, Asymptomatic, Serum.

Interpretation
All specimens with signal-to-cutoff ratios of 1.0 or greater will be considered reactive and reflex to the hepatitis C virus (HCV) antibody confirmatory test by line immunoassay (HCVL / Hepatitis C Virus Antibody Confirmation, Serum) at an additional charge. Additional testing is needed to differentiate between past (resolved) and chronic hepatitis C.
A negative screening test result does not exclude the possibility of exposure to or infection with HCV. Negative screening test results in individuals with prior exposure to HCV may be due to antibody levels below the limit of detection of this assay or lack of reactivity to the HCV antigens used in this assay. Patients with recent HCV infections (<3 months from time of exposure) may have false-negative HCV antibody results due to the time needed for seroconversion (average of 8 to 9 weeks).
