Hepatitis C Virus Genotyping

CERNER / EPIC MNEMONIC: HCV TYPE
CPT CODE:

87902

TEST INFORMATION: The test is used to determine the genotype, with subtype, of Hepatitis C Virus RNA.
DAYS PERFORMED:

Every 2 weeks

TURNAROUND TIME:

7-14 days

SPECIAL INSTRUCTIONS: The specimen MUST be frozen within 6 hours of specimen collection.
CONTAINER TYPE:

Red top Vacutainer® tube or SSTTM tube

SPECIMEN REQUIREMENTS: Blood (serum)
REJECTION CRITERIA: Excessive hemolysis, gross contamination of specimen, chylous serum, improper storage of specimen, specimen not frozen within 6 hours of collection, inappropriate specimen container, insufficient specimen volume.
MINIMUM VOLUME:

2 mL blood (1 mL serum)

HANDLING INSTRUCTIONS:

Serum MUST be separated and frozen at minus 20°C within 6 hours of specimen collection.

REFERENCE RANGE: The assay will identify the six major HCV genotypes and their subtypes.
LIMITATIONS OF TEST: The assay utilizes amplified HCV RNA. Specimens with insuffucient RNA levels CANNOT be genotyped. New genotypes and subtypes are continually being discovered. Specimens containing a genotype NOT identified by the assay will be referred for additional testing. An additional charge will be generated.
METHODOLOGY:

Polymerase Chain Reaction (PCR)
