Test Details

Methodology

Quantitative test: cobas® HBV for use with cobas® 6800/8800 system

Genotype test (reflex): Polymerase chain reaction (PCR) amplification and DNA sequencing

Result Turnaround Time

7 - 12 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 quantitates HBV DNA in serum or plasma with reflex to HBV genotype and drug resistance testing if ≥500 IU/mL is detected.

Limitations

The quantitative test has a range of 10 IU/mL to 1,000,000,000 IU/mL. The genotype assay is only triggered when the quantitative test result is ≥500 IU/mL.

Specimen Requirements

Specimen

Plasma or serum, frozen

Volume

3 mL

Minimum Volume

1.5 mL (Note: This volume does not allow for repeat testing.)

1.5 mL

1.5 mL (Note: This volume does not allow for repeat testing.)

Container

Red-top tube, gel-barrier tube, lavender-top (EDTA) tube, or PPT. Do not use green-top (heparin) or yellow-top (ACD) tube

Collection Instructions

Centrifuge sample within six hours of collection. Transfer the serum/plasma to a screw-top polypropylene tube and freeze.

Storage Instructions

Freeze.

Causes for Rejection

Green-top (heparin) or yellow-top (ACD) tubes used for collection; serum/plasma not frozen; PPT not centrifuged
