HelpTest Code HCVSP Hepatitis C Virus (HCV) Antibody Screen Prenatal, Serum
Ordering Guidance
This test is intended for testing either symptomatic or asymptomatic women who are pregnant.
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.
Specimens that are repeatedly reactive by screening tests should be confirmed by a more hepatitis C virus (HCV)-specific test. Order HCVRP / Hepatitis C Virus (HCV) RNA Detection and Quantification by Real-Time Reverse Transcription-PCR (RT-PCR), Prenatal, 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 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 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
Specimen Volume: 1.3 mL
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 of pregnant women for hepatitis C virus (HCV) infection in primary care settings, with or without risk factors for hepatitis C
This test should not be used as a screening 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 testing by reverse transcription polymerase chain reaction will be performed at an additional charge.
