Diagnosis / Prognosis - GeneXpert HBV DNA Viral Load Assay
Diagnosis / Prognosis - Dried Blood Spot HBV DNA test

Chronic hepatitis B - 300 patients diagnosed with chronic hepatitis B will be enrolled. A fingerstick HBV DNA test will be performed using the Xpert HBV Viral Load assay, and a dried blood spot sample will be collected which will be tested using a gold standard HBV DNA viral load assay. Both results will be compared against the HBV DNA viral load from standard of care venous blood using the gold standard HBV DNA viral load assy. Enrolment of HBV DNA undetectable participants will be capped at 100.


Diagnosis / Prognosis: GeneXpert HBV DNA Viral Load Assay
The Xpert venous blood HBV DNA viral load assay will be adapted to operate using fingerstick capillary blood samples.

Diagnosis / Prognosis: Dried Blood Spot HBV DNA test
HBV DNA viral load will be measured from a fingerstick capillary dried blood spot sample using a gold standard HBV DNA viral load assay

Summary
Brief summary
This is a cross sectional observational study to asses the performance of two novel HBV DNA
testing methodologies; a) dried blood spot sampling and b) fingerstick capillary blood using
the Xpert® Hepatitis B Virus viral load assay. Both novel testing methodologies will be
compared with venous blood tested using a gold standard HBV DNA assay. The sensitivity and
specificity of the two novel testing will be evaluated.

HBV viral load tests are essential to guide antiviral treatment eligibility and
effectiveness. However, many people are unable to access these tests, particularly those
living in remote or limited resources settings given high cost, or unavailable
infrastructure. Simple, affordable and accessible HBV viral load tests are required to
increase global access to HBV testing and treatment to meet the WHO HBV elimination targets.
The GeneXpert Diagnostic Systems, the most common molecular point-of-care platform globally,
has the potential to provide simple and affordable HBV viral load tests. Dried Blood Spot
testing is also an affordable and accessible testing methodology particularly suited to
remote and resource limited settings. This proof-of-concept study will assess the feasibility
and diagnostic performance of Xpert® HBV Viral Load test and Dried Blood Spot testing for the
quantitation of HBV DNA from fingerstick capillary samples.
