Test Details

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.

Methodology

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

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

Specimen Requirements

Specimen

Plasma or serum, frozen

Volume

3 mL

Minimum Volume

1.5 mL

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

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
