DPC's Immunoassay Workcell Now Available.

LOS ANGELES -- Diagnostic Products Corporation (NYSE:DP) today announced that they have recently begun shipping the Immunoassay Workcell, a high volume automated immunoassay testing system. An extensive testing program and a controlled launch plan have proven the reliability of the system and demonstrated its ability to significantly improve laboratory productivity.

DPC's Sample Management System (SMS) is used to create the Immunoassay Workcell, which combines two IMMULITE 2000 systems, two IMMULITE 2500 systems, or a combination of the two systems. The Immunoassay Workcell is designed to meet the needs of the high volume testing facilities to provide flexibility with productivity for immunoassay testing. The system operator now has access to 48 different assays and 9,600-reagent tests from a single sample entry point, allowing up to 5 hours of usable walk-away time. A unique advantage of the Immunoassay Workcell is that it processes patient samples on a tube-by-tube basis, as opposed to the more conventional rack loading technique. The Immunoassay Workcell also simplifies operation by allowing the laboratory technician to interface with the entire system via a single workstation.

"This is great news for both DPC and our customers," said Sidney A. Aroesty, President, COO, DPC. "With approximately 4,000 IMMULITE 2000 and IMMULITE 2500 systems placed worldwide, it is clear that these systems are meeting the needs of many laboratories in a variety of testing environments. The addition of our Immunoassay Workcell will offer even more flexibility in processing immunoassay tests and will increase productivity and provide operators more usable walk-away time to perform other duties in the lab. The fact that the SMS can be linked to a track-based laboratory automation system further expands our flexibility to meet the needs of our customers. This is the 'powerhouse' in the family of IMMULITE systems."
