| SPECIMEN REQUIREMENTS | ||||
|---|---|---|---|---|
| Specimen | Specimen Volume (min) | Specimen Type | Specimen Container | Transport Environment |
| Preferred | 2 mL (1 mL) | Plasma | EDTA (Lavender Top) | Frozen |
| Instructions | Specimen Type: Ship in plasma preparation tube (PPT(TM)) OR screw-capped polyproplylene frozen transport tubes. Specimen Storage: FREEZE Specimen Collection: Collect specimen in two PPT(TM) tubes, gel-barrier tubes, or lavender-top (EDTA) tubes. Do NOT use green-top (heparin) tubes. Centrifuge specimen within six hours of collection, remove serum/plasma and transfer specimen to polyproplylene screw-capped tubes, and FREEZE. Specimens drawn into PPT(TM) tubes 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. Special Instructions: Please indicate the patient's HCV genotype (1a or 1b) on the test request form. SUBMIT A SEPARATE FROZEN SPECIMEN FOR EACH TEST ORDERED. |
