The Axial Separation Module (ASMTM), which separates whole-blood specimens serially in Axial Process Containers (APCTM), was evaluated for clinical performance at the University of Virginia Health Sciences Center (UVA HSC) in a community-based outpatient laboratory (North Ridge Clinic). We hypothesized that moving the task of blood separation to point of care would reduce specimen turnaround time within the main laboratory. Blood drawn into an APC was separated in the ASM at point of care at the North Ridge Clinic. Blood drawn into a Vacutainer TubeTMwas separated in a conventional centrifuge at the main laboratory. Turnaround time was calculated for the "chem 17" test from files stored in our laboratory information system. Blood serially separated at point of care yielded turnaround time savings for specimens originating from the North Ridge Clinic. Average turnaround time decreased by 24%. Phlebotomists found no appreciable workload increase from incorporating the ASM as a point-of-care blood separation device. Phlebotomists also found that they could immediately detect hemolysis. We concluded that serial separation at point of care reduces specimen turnaround time at the main laboratory. The ASM/APC was found to be better suited for point-of-care blood separation than a conventional centrifuge. We speculate that immediate blood separation has the potential to improve the quality of analytical results.


Key Words: indexing terms: automation • centrifugation • hemolysis • turnaround time • axial separation
