The tests run on the firm's sample-to-result automated molecular diagnostics instruments designed for use by high-volume labs.

The firm said its new molecular platform, which offers random-access testing, high throughput, and a broad menu has the potential to replace multiple instruments in molecular labs.

The test measures hepatitis B viral DNA and is intended to be used to assess prognosis and response to antiviral therapies.

The assay is designed to quantitate HBV DNA in serum or plasma to assist in the treatment of chronic HBV-infected patients receiving antiviral therapy.
