Test ID: HCVDX
Hepatitis C Virus (HCV) Antibody with Reflex to HCV RNA, PCR, Symptomatic, Serum
Testing Algorithm 
Delineates situations when tests are added to the initial order. This includes reflex and additional tests.
If hepatitis C virus (HCV) antibody screen is reactive, then HCV RNA by reverse transcription-polymerase chain reaction (RT-PCR) will be performed at an additional charge.
See Hepatitis C: Testing Algorithm for Screening and Diagnosis in Special Instructions.
Specimen Type Describes the specimen type validated for testing
Ordering Guidance
This test is not intended for testing asymptomatic individuals (ie, screening purposes). For testing such patients with or without risk factors for hepatitis C virus (HCV) infection, order HCSRN / Hepatitis C Virus (HCV) Antibody Screen with Reflex to HCV RNA, PCR, Asymptomatic, Serum.
For testing autopsy/cadaver or hemolyzed specimens, order HCCAD / Hepatitis C Virus Antibody Screen for Cadaveric or Hemolyzed Specimens, Serum for asymptomatic individuals or HCCDD / Hepatitis C Virus Antibody in Cadaveric or Hemolyzed Specimens, Serum for symptomatic individuals.
For patients with acute or recent HCV infections (<3 months from time of exposure) or are repeatedly reactive by screening tests and should be confirmed by a more HCV-specific test, order HCVQN / Hepatitis C Virus (HCV) RNA Detection and Quantification, Real-Time Reverse Transcription-PCR (RT-PCR), Serum.
Shipping Instructions
If shipment will be delayed for >24 hours, freeze serum at -70 degrees C until shipment on dry ice.
