Bio-Rad Signs Two Multi-Year Agreements with Quest Diagnostics

Bio-Rad Laboratories, Inc. (AMEX: BIO and BIOb), a multinational manufacturer and distributor of life science research and clinical diagnostics products, announced today that the company has signed two multi-year agreements with Quest Diagnostics Incorporated (NYSE: DGX) to place BioPlex^® 2200 systems and autoimmune test reagents as well as Bio-Rad's HIV-1/HIV-2 PLUS O EIA assay, which allows Quest Diagnostics to detect HIV-1 and HIV-2 in their network of reference laboratories nationwide. Terms of the agreements were not disclosed.

The BioPlex 2200 system is the first and only fully-automated random access testing system employing multiplex technology to simultaneously generate multiple results from a single small patient sample. Introduced last year, the BioPlex 2200 system brings the benefits of full automation and random access capability to labor intensive specialty testing areas such as autoimmune and serology. In early April, Bio-Rad announced that it had released Epstein Barr Virus kits to run on the BioPlex 2200 system and that it has more than 15 other multiplex reagent kits in development for the system.

"We are excited to work with Quest Diagnostics and are confident that the BioPlex 2200 system will serve them well by enhancing their already outstanding reputation for high quality testing and excellent service to their clients," said Norman Schwartz, Bio-Rad President and Chief Executive Officer. "Quest will be the first national reference lab in the country to offer the BioPlex ANA Screen. As a result, clinicians and patients will benefit from broad access to this innovative technology."
