Impact of the new Beckman Coulter Cytomics FC 500 5-color flow cytometer on a regional flow cytometry clinical laboratory service.

Calgary Laboratory Services (CLS) in Alberta, Canada, is the regional reference laboratory providing flow cytometry services for southern Alberta and southeastern British Columbia. As a busy reference flow laboratory we provide flow cytometry immunophenotyping for investigation and diagnosis of acute and chronic leukemias, lymphomas, immunodeficiencies, neuroblastoma, platelet disorders, and interstitial lung disease (ILD). Because of increasing workload and the continual effort to improve the service to our health care providers, CLS invested in the new Beckman Coulter Cytomics FC 500 5-color flow cytometer. In addition to time and labor savings due to reduced maintenance and operating system design, this new flow cytometer automates many of the previous manual steps involved in quality control and flow cytometric analysis. It also incorporates 2 lasers and is capable of measuring 5-color antibody combinations in a single tube, enabling us to reduce the number of tubes and overall costs, giving us better gating options for minimal residual disease analysis. We present the first published evaluation, an assessment of the overall productivity and cost impact of the new state-of-the-art Cytomics FC 500 flow cytometer. Implementation of the Cytomics FC 500 has resulted in a 20% reduction in reagent costs and shorter turnaround time for analysis and diagnosis. This instrument has allowed us to reduce our acute leukemia panel from 17 to 13 tubes, our lymphoma panel from 13 to 7 tubes, and our ILD panel from 4 to 2 tubes. The availability of 2 lasers provides more flexibility in choosing antibodies and conjugates to customize immunophenotyping panels. It also allows us to use the DRAQ5 dye and simultaneously analyze the immunophenotype and DNA content of cells with very little compensation. Many of the arduous, time-consuming flow operator tasks often associated with previous generation flow cytometry instruments, such as color compensation, list mode analysis, sample repeats, and interpretations, have been substantially reduced with the Cytomics FC 500 5-color flow cytometer. In conclusion the Cytomics FC 500 5-color flow cytometer is a major advance in flow cytometry instrumentation and has reduced our overall reagent costs by 20%, provided better information and speedier turnaround time to our health care professionals. It is an ideal flow cytometer for any busy clinical or research flow cytometry service.
