Test Details
Methodology
cobas® HBV for use on the cobas® 6800/8800 system
Result Turnaround Time
2 - 4 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.
Special Instructions
Submit the patient's Social Security number for serial monitoring. To order this test without the serial monitor service, use test 551610.
Limitations
The HBV quantitative real-time PCR assay has a quantitative range of 10 to 1,000,000,000 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 |
Refrigerated | 6 days |
Frozen | 12 weeks |
Note: Stability provided by manufacturer or literature reference.
Storage Instructions
Freeze (preferred) or refrigerate.
Causes for Rejection
Incorrect anticoagulant; PPT™ not centrifuged
