HBV Genotype Quantitative
Hepatitis B Virus (HBV) Genotyping Plus Drug Resistance
HBV Genotype, PreCore and Resistance
HBV Resistance Testing
Data generated in the genotyping assay is subsequently analyzed for mutations in the reverse transcriptase gene of HBV associated with resistance to therapeutic agents, and if identified an interpretation of their clinical significance provided.
This assay may not be successful when the HBV viral load is <500 IU/mL.
Plasma or serum, frozen
Gel-barrier tube, yellow-top (ACD) tube, lavender-top (EDTA) tube or PPT.
Centrifuge sample within six hours of collection, transfer plasma/serum to a polypropylene screw-cap tube and freeze. To avoid delays in turnaround time, when requesting multiple tests on frozen samples, please submit separate frozen specimens for each test requested.
Quantity not sufficient for analysis; heparin/SPS plasma (wrong anticoagulant); gross hemolysis; specimen not frozen
