Hepatitis C Genotype

  • One SST

Also Acceptable:
  • One Lavender (EDTA)
  • One Pink Top (EDTA)
  • One Red Top
  • 3 mL (Min:2 mL) Serum . Submit Frozen. Submit in a Standard Transport Tube.

Also Acceptable:
  • 3 mL (Min:2 mL) Plasma . Submit Frozen. Submit in a Standard Transport Tube.
Special Handling:
  • Avoid Repeated Freeze/Thaw Cycles
  • Separate aliquot required for each frozen test ordered
  • Separate from cells ASAP
  • Specimens sent to Interpath Laboratory for HCV Genotyping must have been tested for the presence of HCV RNA (Hepatitis C RNA Quant by PCR, test 2680) and have had a minimum viral load of 1000 IU/mL. Hepatitis C RNA Quant by PCR w/Reflex (test 2685) provides for this requirement, reflexing to Hepatitis C Genotype if the above criteria is met, and an additional charge is added. This assay incorporates ferrocene-labeled signal probes to detect the six major HCV genotypes and their most common subtypes (1a, 1b, 2a/c, 2b, 3, 4, 5, 6). Rare genotypes may not be detected.
Stability:Ambient: 6 Hour(s); Refrigerated: 3 Day(s); Frozen: 1 Month(s); Incubated: Unacceptable
  • eSensor HCVg Direct, Multiplex Reverse Transcription-PCR amplification
Reported:3-8 Day(s)
Testing is performed once per week, and takes two days to complete, beginning on Thursday morning, completing on Friday afternoon.
CPT Codes:
  • 87902
Interpretive Data:

Assay methodology is Multiplex Reverse Transcription-PCR amplification using eSensor HCVg Direct cartridges to test for the identification of Hepatitis C RNA Genotype using the GenMark XT-8. The following subtypes are tested for: 1a, 1b, 2a/c, 2b, 3, 4, 5, and 6. This test was developed and its performance characteristics have been determine by Interpath Laboratory, Inc. It has not been cleared or approved by the U.S. Food and Drug Administration. The FDA has determined that such clearance or approval is not necessary . The results are not intended to be used as the sole means for clinical diagnosis or patient management decisions.

A sample is required to have a minimum HCV Viral Load of 1000 IU/mL in order to be tested for an HCV Genotype. Insufficient viral loads may not be able to provide a Genotype.
