Test Code HCVL Hepatitis C Virus Antibody Confirmation, Serum

Useful For

Confirming the presence of hepatitis C virus (HCV)-specific IgG antibodies in serum specimens that are reactive by HCV antibody screening tests

 

Distinguishing between true- and false-reactive HCV antibody screening test results

 

This test is not intended for use as an HCV antibody screening test for blood or human cells/tissue donors.

 

This assay is not useful for detection of early or acute hepatitis C (<2 months from exposure) as immunocompromised patients may not develop detectable HCV antibodies in blood until 6 months after infection.

 

This assay is not useful for differentiating between past (resolved) and chronic hepatitis C.

Testing Algorithm

This test is available as a confirmatory test for reactive Hepatitis C virus (HCV) antibody screening test results.

Ordering Guidance


This test does not differentiate between past (resolved) and chronic hepatitis C. To distinguish between past (resolved) and chronic hepatitis C, order HCVQN / Hepatitis C Virus (HCV) RNA Detection and Quantification by Real-Time Reverse Transcription-PCR (RT-PCR), Serum.

 

For screening of asymptomatic individuals for HCV, order HCSRN / Hepatitis C Virus (HCV) Antibody Screen with Reflex to HCV RNA, PCR, Asymptomatic, Serum.

 

For detection of HCV in symptomatic at-risk individuals, order HCVDX / Hepatitis C Virus (HCV) Antibody with Reflex to HCV RNA, PCR, Symptomatic, Serum.
