                            Receives FDA Approval for Second-GenerationHepatitis B Viral Load Test
 Improved 
                            viral load testing with a sensitive and fully automated 
                            system  Pleasanton, 
                            CA -- September 22, 2010 -- Roche Molecular Diagnostics 
                            (SIX: RO, ROG; OTCQX: RHHBY) announced today that 
                            the U.S. Food and Drug Administration (FDA) has approved 
                            the COBAS AmpliPrep/COBAS TaqMan HBV Test v2.0 for 
                            use in the United States. The new Roche test provides 
                            a fully automated solution for the quantitative detection 
                            of hepatitis B virus (HBV) DNA in human plasma or 
                            serum for patients on HBV antiviral therapy.
 "This 
                            new test enables clinicians to follow best practices 
                            in patient care with standardized viral load measurements, 
                            a broad range of detection, and high sensitivity," 
                            said Paul Brown, PhD, President and CEO of Roche Molecular 
                            Diagnostics. "The system is also carefully designed 
                            to protect the integrity of each patient result, so 
                            clinicians can make key medical decisions about therapy 
                            with confidence."  According 
                            to the Centers for Disease Control, an estimated 1.2 
                            million people in the United States are living with 
                            chronic hepatitis B. Clinical practice guidelines 
                            for chronic HBV highlight the importance of monitoring 
                            the levels of circulating hepatitis B viral DNA as 
                            an indicator of when hepatitis B therapies should 
                            be started, and to measure response to treatment, 
                            including suppression of HBV replication.
 "Viral load testing remains the gold-standard 
                            for the management of HBV antiviral therapy," 
                            said Teresa Wright, MD, Chief Medical Officer of Roche 
                            Molecular Diagnostics. "Roche's new HBV test 
                            provides accurate and reproducible results at the 
                            key medical decision points, allowing the clinician 
                            to optimize patient outcomes."
 
 About the COBAS AmpliPrep/COBAS TaqMan HBV Test 
                            v2.0
 
 The Roche COBAS AmpliPrep/COBAS TaqMan HBV Test v2.0 
                            has been validated to quantify diverse samples from 
                            genotypes A-H and pre-core mutants across a broad 
                            linear dynamic range of 20 IU/mL to 1.7E+08 IU/mL. 
                            The new assay uses a reduced sample input volume of 
                            650 mcL of either serum or plasma specimens and is 
                            standardized against the World Health Organization 
                            (WHO) standard for hepatitis B.
 
 This test is designed for use on Roche's fully automated 
                            COBAS AmpliPrep/COBAS TaqMan System that is used in 
                            more than 250 clinical laboratories across the U.S.
 
 The platform combines the COBAS AmpliPrep Instrument 
                            for automated sample preparation and the COBAS TaqMan 
                            Analyzer or the smaller COBAS TaqMan 48 Analyzer for 
                            automated real-time PCR amplification and detection.
 
 "Sample in/results out" testing eliminates 
                            manual intervention between steps and configuration 
                            options allow for customizable solutions for throughput 
                            needs. For a flexible throughput solution, the test 
                            offers 72 tests per kit in self-sealing, ready-to-use 
                            reagent cassettes. Roche's proprietary AmpErase enzymes 
                            are also included in each test and are designed to 
                            prevent cross-contamination of samples and labs.
