Interpretive Data
Both the HBV RT polymerase and the HBsAg encoding regions are sequenced. Resistance and surface antigen mutations are reported. In addition, the eight major HBV genotypes (A, B, C, D, E, F, G and H) are identified. Mutations in viral sub-populations below 20 percent of total may not be detected.

This test is performed pursuant to a license agreement with Roche Molecular Systems, Inc.

See Compliance Statement B: www.aruplab.com/CS  
Note
This test may be unsuccessful if the HBV viral load is less than log 3.0 or 1,000 IU/mL of plasma.
