BioPlex 2200 Streamlines Vasculitis Testing


Novel Automated Multiplexing Technology Streamlines Vasculitis Testing and Maximizes Laboratory Efficiency

HERCULES, CA - February 11, 2008 - Bio-Rad Laboratories, Inc. (AMEX: BIO and BIOb), a multinational manufacturer and distributor of life science research and clinical diagnostic products, today announced the launch of the first and only fully-automated, random access multiplex test system for autoimmune systemic vasculitis testing. The BioPlex® 2200 Vasculitis kit is for use on the BioPlex 2200 system, a platform that employs multiplexing technology to analyze multiple disease markers from a single patient sample.

Vasculitis is an autoimmune disease in which the body's immune system mistakenly attacks its own blood vessels causing them to become inflamed. The disruption of blood flow can result in damage to a body's organs. Through simultaneous identification and semi-quantitative detection of three of the most clinically relevant vasculitis autoantibodies, the BioPlex 2200 Vasculitis kit can be used help diagnose some of the most severe autoimmune vasculitis diseases.

"The release of the Vasculitis kit is another example of Bio-Rad's continued commitment to provide laboratories with more useful information, highly reproducible results, and faster result turnaround time," said John Goetz, Bio-Rad Vice President and Group Manager Clinical Diagnostics. "Using the Vasculitis kit, physicians are able to offer enhanced patient management while optimizing their operational efficiencies and reducing costs."

The BioPlex 2200 system is the first and only fully-automated, random access multiplex testing system and provides clinical laboratories with the capability to rapidly process or "multiplex" multiple individual tests, which are traditionally processed separately, using a single small volume patient sample.
