HEPATITIS C VIRUS (HCV) GENOTYPING NONREFLEX

General Information

HLAB/HOL Code: HCVGN
UPHSM LIS Test #: 5914
Schedule:
Testing Time:
Testing Lab: Labcorp

Specimen Info
Only 1 specimen type required, unless otherwise specified

Volume: 3.0 (2.5) mL plasma or serum
Temperature: Frozen
Tube Type: Serum or Plasma
Collection Info:
Special Instructions:  A separate frozen specimen is required for each frozen test ordered. Only submit samples that contain a HCV viral load >600 IU/mL serum or plasma.

Collection:  Collect specimen in gel-barrier tube, PPT™, yellow-top (ACD) tube, or lavender-top (EDTA) tube. Do not use green-top (heparin) tubes. Separate serum or plasma from whole blood within six hours of blood collection. Remove serum or plasma, transfer to a screw-cap polypropylene tube (not “pop top” or “snap cap”), and freeze. Specimens drawn into PPT™ need to be centrifuged within six hours and frozen. Ship frozen. To avoid delays in turnaround time when requesting multiple tests on frozen samples, please submit separate frozen specimens for each test requested.

Storage Instructions:  Freeze at -20°C.

Causes for Rejection:  Hemolysis; green-top (sodium heparin) tube; specimen not frozen on date of collection; PPT™ not centrifuged; specimen received in “pop-top” or “snap-cap” tube; specimen shipped at room temperature

Methods

Polymerase chain reaction (PCR) amplification and line probe hybridization

Clinical Utilities

Use:  This assay, for in vitro use, is intended for the genotyping of hepatitis C virus (HCV) in human serum and plasma. This test allows genotyping of the six major HCV types and their most common subtypes.

Limitations:  This procedure may not be successful when the HCV viral load is <600 IU/mL serum or plasma. As a QC measure, viral load is confirmed on samples that fail genotyping.
