Test ID HCVQN Hepatitis C Virus (HCV) RNA Detection and Quantification by Real-Time Reverse Transcription-PCR (RT-PCR), Serum

Ordering Guidance

For detection and quantification of HCV RNA in serum before, during, and after antiviral therapy for chronic hepatitis C.

Shipping Instructions

1. Freeze serum immediately, and ship specimen frozen on dry ice only.

2. If shipment will be delayed for more 24 hours, freeze serum at -20 to -80° C (up to 84 days) until shipment on dry ice.

Specimen Required

Supplies: Aliquot Tube, 5 mL (T465)

Collection Container/Tube: Serum gel

Submission Container/Tube: Polypropylene vial (T465)

Specimen Volume: 1.5 mL

Collection Instructions:

1. Centrifuge blood collection tube per collection tube manufacturer's instructions.

2. Pour off serum into aliquot tube.

Useful For

Detection of acute hepatitis C virus (HCV) infection before the appearance of HCV antibodies in serum (ie, <2 months from exposure)


Detection and confirmation of chronic HCV infection


Quantification of HCV RNA in serum of patients with chronic HCV infection (HCV antibody-positive)


Monitoring disease progression in chronic HCV infection and response to antiviral therapy


Determining cure and detection of relapse after completion of antiviral therapy


A reflex test for serum specimens that are hepatitis C Virus (HCV) antibody screen-reactive for diagnosis of chronic hepatitis C.


This test is appropriate for diagnosis of acute hepatitis C in high-risk or immunosuppressed individuals who may be negative for HCV antibodies.


This test can be used to establish a baseline HCV viral load before initiating antiviral therapy for chronic hepatitis C.


This test can be used to monitor response and progress during antiviral therapy for chronic hepatitis C.


This test is appropriate for confirming a sustained virologic response and detecting a relapse of hepatitis C after completion of antiviral therapy.
