Test ID: HCVQG
Hepatitis C Virus (HCV) RNA Quantification with Reflex to HCV Genotype, Serum
Useful For 
Suggests clinical disorders or settings where the test may be helpful
Detection of acute HCV infection before the appearance of HCV antibodies in serum (ie, <2 months from exposure)
Detection and confirmation of chronic HCV infection, and determining HCV genotype (1 to 5) to guide antiviral therapy in patients with chronic hepatitis C
Quantification of HCV RNA in serum of patients with chronic HCV infection (HCV antibody-positive) before initiating antiviral therapy
Determining cure and detection of relapse of HCV infection after completion of antiviral therapy
Highlights
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 and viral genotype before initiating 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.
Reflex Tests Lists tests that may or may not be performed, at an additional charge, depending on the result and interpretation of the initial tests.
| Test ID | Reporting Name | Available Separately | Always Performed |
|---|---|---|---|
