Outcome Measures

Primary Outcomes (1)

  • Sensitivity and specificity of the Xpert® HBV DNA fingerstick point of care assay

    To evaluate the sensitivity and specificity of the Xpert® HBV DNA point of care assay from finger-stick whole blood samples compared to plasma samples collected via venipuncture and tested on the Roche COBAS AmpliPrep/COBAS TaqMan HBV (CAP/CTM HBV) V2 assay.

    Through study completion, an average of 1 year

Secondary Outcomes (2)

  • Sensitivity and specificity of the point of care ALT

    Through study completion, an average of 1 year

  • Sensitivity and specificity of the Xpert® HBV DNA point of care assay on dried blood spots

    Through study completion, an average of 1 year

Study Arms (2)

A

Not currently on antiviral therapy for HBV and HBV DNA detectable

Diagnostic Test: Xpert® HBV DNA fingerstick point of care assayDiagnostic Test: Point of Care ALTDiagnostic Test: Xpert® HBV DNA point of care assay from dried blood spot

B

Stable on HBV antiviral therapy for at least 3 months with HBV DNA \< 20 IU/ml
