Order before initiating hepatitis C virus (HCV) therapy to aid in prognisos and therapy selection when a higher level of subtype resolution is required (ie, non 6a/b vs. type 1 and type 1a vs. 1b). Do not order prior to molecular confirmation of positive HCV screen.
- Patient Preparation
- Lavender (EDTA), pink (K2EDTA), plasma preparation tube, or serum separator tube (SST).
- Specimen Preparation
- Separate serum or plasma from cells within 6 hours. Transfer 2 mL serum or plasma to an ARUP Standard Transport Tube. (Min: 0.5 mL)
- Storage/Transport Temperature
- Unacceptable Conditions
- Heparinized specimens.
- Please submit most recent viral load and test date if available.
- On cells: Ambient: 6 hours. After separation from cells: Refrigerated: 72 hours; Frozen: 4 months
Isolates of hepatitis C virus are grouped into six major genotypes (1-6). These genotypes are subtyped according to sequence characteristics. Sequencing both the Core and NS5B regions allows for subtyping of all confirmed and most provisional genotypes, including differentiation of 1a from 1b and typing of genotype 6.
