HelpTest ID HCSRN Hepatitis C Virus (HCV) Antibody Screen with Reflex to HCV RNA, PCR, Asymptomatic, Serum
Ordering Guidance
This test is not intended for testing symptomatic individuals (ie, diagnostic purposes). For testing such patients with or without risk factors for hepatitis C virus (HCV) infection, order HCVDX / Hepatitis C Virus (HCV) Antibody with Reflex to HCV RNA, PCR, Symptomatic, Serum.
For testing autopsy/cadaver or hemolyzed specimens, order HCCAD / Hepatitis C Virus Antibody Screen for Cadaveric or Hemolyzed Specimens, Asymptomatic, Serum for asymptomatic individuals or HCCDD / Hepatitis C Virus Antibody in Cadaveric or Hemolyzed Specimens, Symptomatic, 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 by Real-Time Reverse Transcription-PCR, Serum.
If testing is desired to distinguish between true positivity and biologic false positivity for HCV antibody, then testing may be done with a second HCV antibody assay approved by the US Food and Drug Administration for diagnosis of HCV infection that is different from the assay used for initial antibody testing (HCCAD / Hepatitis C Virus Antibody Screen for Cadaveric or Hemolyzed Specimens, Asymptomatic, Serum).
Shipping Instructions
If shipment will be delayed for more than 24 hours, freeze serum at -70° C until shipment on and transport on dry ice.
Necessary Information
Date of collection is required.
Specimen Required
Patient Preparation: For 24 hours before specimen collection, patient should not take multivitamins or dietary supplements (eg, hair, skin, and nail supplements) containing biotin (vitamin B7).
Supplies: Sarstedt Aliquot Tube, 5 mL (T914)
Collection Container/Tube: Serum gel (red-top tubes are not acceptable)
Submission Container/Tube: Plastic vial

Collection Instructions:
1. Centrifuge blood collection tube per manufacturer's instructions (eg, centrifuge and aliquot within 2 hours of collection for BD Vacutainer tubes).
2. Aliquot serum into plastic vial.
Useful For
Screening for hepatitis C virus (HCV) infection in primary care settings in high-risk persons with a current or previous history of illicit injection drug use or a history of receiving a blood transfusion prior to 1992
Screening for hepatitis C in primary care settings in non-high-risk persons born from 1945 through 1965
Screening at least once in a lifetime for all adults greater or equal to 18 years, except in settings where the prevalence of HCV infection is less than 0.1%
This test is not offered as a screening or confirmatory test for hepatitis C in blood or human cells/tissue donors.
This test profile is not useful for detection or diagnosis of acute hepatitis C, since HCV antibodies may not be detectable until after 2 months following exposure and HCV RNA testing is not performed on specimens with negative HCV antibody screening test results.
Testing Algorithm
If the hepatitis C virus (HCV) antibody screen is reactive, then HCV RNA by reverse transcription polymerase chain reaction) will be performed at an additional charge.
