Assay methodology is polymerase chain reaction (PCR) using the ROCHE COBAS TaqMan® Analyte Specific Reagent. Results below the limit of detection (1.9 log IU/mL) will be reported as <1.9 log IU/mL. Results between 1.9 and 2.3 log IU/mL (75 to 200 IU/mL) will be reported as "HCV RNA detected below the limit of quantitation." Results 2.3 log IU/mL (200 IU/mL) and greater will be reported with a numeric value. False positive results may occur. A result of less than 75 HCV IU/mL does not rule out the presence of PCR inhibitors in the patient specimen or hepatitis C virus RNA concentrations below the level of detection by the assay. This assay should not be used for blood donor screening, associated re-entry protocols, or for screening Human Cell, Tissues and Cellular Tissue-Based Products (HCT/P). Please refer to Statement A in the Compliance Statements section in the front of the Laboratory Test Directory. *ExistInterpData> |

| A qualitative PCR assay with a detection limit of 50 HCV RNA IU/mL is available for the assessment of lower levels of HCV viremia, (refer to test Hepatitis C Virus RNA Qualitative PCR 0098264). |
