BACKGROUND A new immunoanalyzer (AU3000i) has been developed by Olympus (Rungis, France) with the intention of offering a consolidated workcell. The aim of this experiment was to assess, in a multi-centre study (two French sites, one German site), the practicability of the Olympus AU3000i in terms of throughput (test/h), rerun capabilities, emergency sample handling and reflex test capabilities. RESULTS The workload study showed that the AU3000i was capable of running both one- and two-step assay protocols with a throughput of 240 tests per hour which corresponds to 209.3 tests per hour including the initialization time. Emergency samples were correctly treated as a priority in less than 30 minutes for ten samples. Furthermore the analyzer could be programmed to generate automatic dilution, rerun and reflex tests, reducing the hands-on labour time for technicians. CONCLUSIONS Workflow studies showed that Olympus AU3000i and AU Clinical Chemistry can cover the combined workload of various routine analyzers in a variety of laboratory environments.
