CPT-4 Code(s)

G0472, plus 87522 if reflexed to HCV PCR, at additional cost

Specimen Information

Performance of the HCV assay has not been established with cord blood or neonatal specimens.

Collect

HCV Antibody Screen: Serum Separator Tube (SST)
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.

Alternate Specimen

HCV Antibody: red top, lavender EDTA (follow Plasma collection guide for PCR), lithium heparin,
sodium heparin
HCV PCR: Serum: red top
*PCR and antibody testing cannot be done on shared specimens. Separate tubes must be clearly
labeled for antibody and PCR specimens.

Minimum Volume

HCV antibody: 0.5 mL
HCV PCR: 2.5 mL

Rejection Criteria

HCV Antibody: gross hemolysis, gross lipemia
HCV PCR: gross hemolysis, gross lipemia, heparin plasma, gel-based plasma separation tubes,
specimens subjected to repeat freeze thaw cycles, shared 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.
