Geisinger Epic Procedure Code: LAB2443         Geisinger Epic ID: 32445

Specimen type:
Serum AND plasma.

Collect two tubes. :

Preferred collection container:
Alternate Collection Container:
6 mL red-top (plain, non-serum separator) tube
Specimen required:
Serum: 1 mL aliquot, minimum 0.5 mL
Plasma: one 3-4 mL plasma aliquot, minimum 2.0 mL NO SHARED SPECIMENS.

Specimen processing instructions:
Allow serum to clot. Centrifuge to separate serum or plasma. If red-top is drawn, serum must be aliquoted. Separate plasma from EDTA whole blood within 24 hours of collection. 
Transport temperature:
Serum: Refrigerated.
Plasma: Frozen -20 to -80°C (preferred). Plasma may also be transported at 2-8°C.
EDTA whole blood: 2-8°C up to 24 hours.
Specimen stability:
Serum: Room temperature: 3 days. Refrigerated: 21 days at 2-8°C. Frozen: 3 months.
Plasma may be stored at 2-8°C up to 6 days, or frozen at -20 to -80°C up to 12 weeks (preferred).
EDTA whole blood samples can be stored at 2-8°C up to 24 hours prior to centrifugation.
Rejection criteria:
Whole blood specimens must be collected in EDTA tubes. Specimens must be separated with 24 hours of collection, or will be rejected. Improper storage or transport temperature. Stability limits exceeded. Shared or comingled specimens. Add-ons available only to unopened tube.

Reference interval:
Negative for antibody screen. Negative IU/mL for HCV RNA quantitation.
Additional information:
Linear Range of the quantitative assay is 15 IU/mL to 100 million IU/mL. Positive results less than 15 IU/mL will be reported as HCV RNA detected, not quantifiable. The lower level of detection (LLoD) of this assay is 12 IU/mL from plasma specimens.
CPT code(s):
86803. When antibody screen is positive, an additional CPT code of 87522 is added for HCV RNA Quantitative Viral Load.
Note: The billing party has sole responsibility for CPT coding.  Any questions regarding coding should be directed to the payer being billed.  The CPT codes provided by GML are based on AMA guidelines and are for informational purposes only.
Chemiluminescence Immunoassay
