General Information
The Alinity m HBV assay is an in vitro polymerase chain reaction (PCR) assay for the quantitation of Hepatitis B Virus (HBV) DNA from HBV-infected individuals over the range of 30 to 1,000,000,000 IU/ml. The assay targets a region on the surface antigen gene which gives the detection of HBV genotypes A, B, C, D, E, F, G, H and I.

Notes
Sample Stability
Please transport samples to the laboratory for testing ASAP. Primary tubes can be tested up to 24hrs after drawing blood as long as the tubes have been kept at +4◦C. Separated plasma samples can be kept at +4◦C for 5 days before testing.
Debris within serum specimens (e.g. clots, fibrin strands) may interfere with sample processing as a result of insufficient mixing on draw.
