    Abstract:
    Our core laboratory at St. Joseph's Medical Center (SJMC) recently installed the new Beckman Coulter LH 1500 fully automated hematology workcell. Like many laboratories in North America and other parts of the world, we are under significant pressure to improve productivity, reduce costs, and improve service provision to our hospital and clinician bases. The difficulty of meeting this challenge is often further compounded by an increasing shortage of qualified technologist personnel. We recently reported on the significant productivity gains with the introduction of the LH 750 hematology system into the core laboratory, including a 23% reduction in slide review rate, automation of reticulocyte and nucleated red blood cell counts, and an 82% increase in the pass-through rate. Evolution to the next stage of automation has come much quicker than anticipated owing to a steep rise in workload and an ever increasing shortage of trained and experienced technologists to fill vacancies in the 24-hour core laboratory operation. We chose to upgrade our LH 750 analyzers to the newly introduced LH 1500 hematology workcell in order to cope with the increased workload and shortage of available experienced hematology technologists. The LH 1500 is a compact, high throughput, fully automated hematology workcell. It is designed to automate all manual process and handling steps associated with hematology analyses, including sample sorting, loading and unloading of cassettes, automatic rerun and reflex testing, sample storage, and tracking of samples. The LH 1500 is comprised of a minimum of 2, and up to 4, LH 750 instruments (with or without integrated slidemaker/stainers). The instruments are bidirectionally interfaced and linked to a fully automated conveyor track, specimen inlet and outlet stations, a sample stockyard, and a line controller. The configuration we chose at SJMC incorporates 1 LH 750 and 1 LH 755. We report that the upgrade to the LH 1500 was a relatively straightforward process and required no redesign of the core laboratory. Based on our evaluation, we estimate cost savings with the LH 1500 of between three quarters to 1 full-time equivalent, which eliminated or decreased many manual handling steps. In addition, this increase in efficiency has freed up our technologist resources to concentrate on the more difficult and clinically important samples. This is the first published report on the new LH 1500 hematology workcell. Our research indicates that the LH 1500 is the first hematology workcell to offer hematology laboratories the next level of automation and virtually eliminate preanalytical and postanalytical sample handling and sorting. For core laboratories and high-throughput hematology laboratories that face similar pressures to ours, the LH 1500 would appear as an attractive solution to maximize hematology productivity and improve service delivery.
