cobas® HBV Test

Confidence and precision at medically relevant decision points
cobas® HBV Test

Delivering on clinical need requirements

Hepatitis B virus (HBV) DNA detection and viral load measurement are essential for treatment decisions and patient monitoring.1 cobas® HBV for use on the cobas® 4800/5800/6800/8800 Systems provides security in your results with primers and probes targeting the highly conserved pre-core and core regions of the HBV genome. The amplified region of the genome will not be affected by mutations that arise due to drug resistance.2

cobas® HBV provides robust, clinically relevant assay performance with a broad linear range and high sensitivity, delivering optimal results throughout critical medical decision points and across all genotypes combined with a highly efficient laboratory workflow.1,3

Roche has been at the forefront of viral load monitoring tests for hepatitis and continues to provide a robust assay design to ensure accurate and reliable results to improve patient management and treatment success.

Features

  • Excellent performance with serum and plasma specimens
  • Built-in contamination control with AmpErase enzyme to prevent carryover contamination
  • Excellent correlation to Roche COBAS® AmpliPrep/COBAS® TaqMan® HBV Test, v2.0

Intended use

Intended use

CE-IVD

cobas® HBV is an in vitro nucleic acid amplification test for the quantitation of hepatitis B virus DNA in human EDTA plasma or serum of HBV-infected individuals.

 

This test is intended for use as an aid in the management of patients with chronic HBV infection undergoing anti-viral therapy. The test can be used to measure HBV DNA levels at baseline and during treatment to aid in assessing response to treatment. The results from cobas® HBV must be interpreted within the context of all relevant clinical and laboratory findings.

US-IVD

cobas® HBV is an in vitro nucleic acid amplification test for the quantitation of hepatitis B virus DNA in human EDTA plasma or serum of HBV-infected individuals.

 

This test is intended for use as an aid in the management of patients with chronic HBV infection undergoing anti-viral therapy. The test can be used to measure HBV DNA levels at baseline and during treatment to aid in assessing response to treatment. The results from cobas® HBV must be interpreted within the context of all relevant clinical and laboratory findings.

 

The cobas® HBV is not intended for use as a screening test for the presence of HBV in blood or blood products or as a diagnostic test to confirm the presence of HBV infection.

A critical assessment tool for long term patient monitoring

Roche hepatitis assays deliver robust, clinically relevant performance with a broad linear range, high sensitivity and optimal results within a fully automated workflow.
