Hepatitis C Virus (HCV), Quantitative, Real-time PCR (Graphical)

CPT 87522
Synonyms
  • HCV RNA Quantitation, TaqMan®

Test Details

Methodology

Cobas® HCV (Roche Molecular Systems)

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

Determine the number of international units (IU) of hepatitis C virus (HCV) RNA per milliliter in serum or plasma in known HCV-positive patients

Special Instructions

Submit the patient's Social Security number for serial monitoring. To order this test without the serial monitor service, order Hepatitis C Virus (HCV), Quantitative, Real-time PCR (Nongraphical) [550080].

Limitations

The quantifiable range of the assay is 15 IU/mL to 100,000,000 IU/mL.

Specimen Requirements

Specimen

Serum or plasma

Volume

2.5 mL

Minimum Volume

700 μL (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.

Stability Requirements

Temperature

Period

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
