Hepatitis C Virus (HCV) by Quantitative NAAT

HEPC QNT
Example Reports
Detected

Ordering Recommendation

Preferred single test to confirm hepatitis C virus (HCV) infection following a positive HCV antibody screen. May also be useful to diagnose suspected acute HCV infection or infection in seronegative immunocompromised individuals.

Interpretive Data

The quantitative range of this test is 15-100,000,000 IU/mL (1.18-8.0 log IU/mL).

A result of "Not Detected" does not rule out the presence of inhibitors in the patient specimen or hepatitis C virus RNA concentrations below the level of detection of the test. Care should be taken when interpreting any single viral load determination.

This test is intended for use as an aid in the diagnosis of HCV infection in the following populations: individuals with antibody evidence of HCV with evidence of liver disease, individuals suspected to be actively infected with HCV antibody evidence, and individuals at risk for HCV infection with antibodies to HCV. Detection of HCV RNA indicates that the virus is replicating and therefore is evidence of active infection.

This test is also intended for use as an aid in the management of patients with an HCV infection undergoing antiviral therapy. The assay can be used to measure HCV RNA levels at baseline, during treatment, at the end of treatment, and at the end of follow-up of treatment to determine sustained or nonsustained viral response. The results must be interpreted within the context of all relevant clinical and laboratory findings.

This test should not be used for blood donor screening, associated reentry protocols, or for screening human cells, tissues and cellular tissue-based products (HCT/P).

Compliance Category

FDA

Note

The limit of quantification for this RNA assay is 15 IU/mL (1.18 log IU/mL). If the assay DETECTED the presence of the virus but was not able to accurately quantify, the test will be reported as "Not Quantified, Detected."
