| Hepatitis C Virus Genotype (8000100238) | |
|---|---|
| Test Mnemonic: | HCV GENO |
| Specimen Requirements: | |
| Collection: | One pearl color (PPT) top Vacutainer or one yellow color (SST) or red top vacutainer; collect one tube for this test and do not combine with other test orders. |
| Container: | PPT or SST |
| Minimum Volume: | 4 ml |
| Storage/Transport: | Transport frozen |
| Specimen Preparation: | Within six hours of collection, centrifuge blood sample at 1,000 x g for 15 minutes. After centrifugation, remove plasma or serum from cells into a screw-cap polypropylene transport tube before freezing plasma in situ in PPT tube or Serum in SST tube or red top tube. |
| Stability: |
• Separated plasma/Serum can be stored for up to 48 hours at 2° to 8°C.
• For longer term storage, freeze samples at -80° to -20°C. Note: Plasma will not be frozen in situ in the BD PPT Tube, or Serum in SST tube or red top tube due to intracellular DNA interferes.
• Thaw only for use. Do not freeze and thaw more than four times prior to processing the specimens
|
| Causes for Rejection: | Incomplete and/or incorrect sample identification, insufficient sample volume, incorrect blood collection tube (Vacutainer), gross hemolysis, clots, prolonged time to processing. Transport at room temperature or refrigerated. |
| Reference Range: | See report |
| Turnaround Time: | 14 days |
| Methodology: | RT-PCR, Sanger sequencing |
| Performed: | Molecular Diagnostics Laboratory |

| Clinical Indication: | Used to direct HCV treatment and predict disease outcome |
| Patient Preparation : | Routine venipuncture |
| CPT 4 Code: | 87902 |
| When ordering tests for which Medicare or Medicaid reimbursement will be sought, physicians should only order tests that are medically necessary for the diagnosis or treatment of the patient. Components of the organ or disease panels may be ordered individually. The diagnostic information must substantiate all tests ordered and must be in the form of an ICD-10 code or its verbal equivalent. | |
