Test Details
Methodology
Cobas® AmpliPrep/Cobas® TaqMan® HCV Test v 2.0. See Hepatitis C Virus (HCV) Genotyping, Nonreflex [550475] for more information.
Result Turnaround Time
3 - 5 days
Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. In some cases, additional time should be allowed for additional confirmatory or additional reflex tests. Testing schedules may vary.
Use
This test is used for quantitation of hepatitis C virus with reflex to HCV genotype if viral load is >1000 IU/mL.
Special Instructions
Submit the patient's Social Security number for serial monitoring. To order this test without the serial monitor service, use test 550090.
Limitations
The quantifiable range of the assay is 15 IU/mL to 100,000,000 IU/mL.

Specimen Requirements
Specimen
Serum or plasma
Volume
3 mL
Minimum Volume
1 mL (Note: This volume does not allow for repeat testing.)
Container
Gel-barrier tube, lavender-top (EDTA) tube, or plasma preparation tube (PPT™)
Collection Instructions
Centrifuge sample within 24 hours of collection. Transfer serum/plasma to a screw-cap polypropylene transport tube. Ship frozen (preferred). Plasma from a PPT™ can be frozen and shipped in situ. To avoid delays in turnaround time when requesting multiple tests on frozen samples, please submit a separate frozen specimen for each test requested.

Room temperature | 24 hours (stability provided by manufacturer or literature reference) |
Refrigerated | 72 hours (stability provided by manufacturer or literature reference) |
Frozen | 6 weeks (stability provided by manufacturer or literature reference) |
Storage Instructions
Freeze (preferred) or refrigerate.
Causes for Rejection
Incorrect anticoagulant; PPT™ not centrifuged
