HCV PCR: Lavender EDTA
*Both specimens required.
Specimen Preparation
HCV Antibody Screen (Label: HCAB) -
Centrifuge, separate serum from cells and send 1.0 mL serum in a screw capped plastic vial.
HCV PCR Plasma (Label: HCVFR):
Centrifuge, separate plasma from cells within 6 hours of collection. Send 3.0 mL plasma in screw
capped plastic vial.
*PCR and antibody testing cannot be done on shared specimens. Separate tubes must be clearly
labeled for antibody and PCR specimens.

Methodology
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.
