HCV Antibody Screen Methodology: Chemiluminscence

HCV RNA, PCR Methodology: Reactive specimens are tested for HCV RNA using a real-time polymerase chain reaction (PCR) test from Abbott Molecular. The amplification target is a conserved region of the HCV genome. The lower limit of quantitation is 12 IU/mL (1.08 Log IU/mL) and the upper limit of quantitation is 100 million IU/mL (8.00 Log IU/mL). The qualitative limit of detection is 12 IU/mL (1.08 Log IU/mL). Specimens reported as "DETECTED" but <12 IU/mL contain detectable levels of Hepatitis C RNA but the viral load is below the quantitation. A "Not detected" result does not rule out infection.

Reference Range

HCV Antibody Screen: Nonreactive
HCV RNA, Qualitative: Not detected
HCV RNA, Quantitative: <12 IU/mL
Log HCV IU/mL: <1.08 Log IU/mL
