Siemens Healthcare Diagnostics ANNOUNCES THE NEXT GENERATION IN AUTOMATED VIRAL LOAD TESTING – THE VERSANT® 440 MOLECULAR SYSTEM APPROVED IN CANADA¹

Walkaway Automation for Increased Productivity and Improved Workflow

Tarrytown, NY, May 16, 2007 – Siemens Healthcare Diagnostics announced today that the VERSANT 440 Molecular System has been approved for marketing by Health Canada for viral load testing of the human immunodeficiency virus (HIV) and the hepatitis C virus (HCV). The enhanced automation of the VERSANT 440 provides laboratories with greater throughput and less hands-on time, maximizing productivity to meet the evolving needs of the clinical laboratory.

The VERSANT 440 Molecular System uses branched DNA technology (bDNA) that simplifies testing by eliminating nucleic acid extraction and removing the risk of cross-contamination. The VERSANT 440 delivers molecular assays for HIV and HCV. Both the VERSANT® HIV-1 RNA and HCV RNA 3.0 Assays demonstrate excellent precision across the entire reporting range, and a high level of reproducibility that allows viral load changes to be distinguished accurately, facilitating patient management. The VERSANT 440 Molecular System is a viral load platform designed for flexible walkaway automation. The system streamlines workflow by integrating bar code data entry, automated reagent processing, detection, and downloadable patient worklist and results through a Laboratory Information System interface software.

¹The VERSANT 440 is not approved by FDA for commercial availability in the United States. VERSANT 440 is CE-Marked in Europe for use with the VERSANT HIV-1 RNA, HCV RNA, and HBV DNA 3.0 assays (bDNA).
