Abstract

Abstract We have evaluated a semi-automated computer controlled dispensing device in conjunction with microtube technology for the performance of routine blood grouping and antibody screening procedures. A total of 787 specimens have been tested, 78 with unexpected antibodies previously identified by manual microtube methods. All were tested in duplicate in different order; there was complete agreement in blood group (ABO, RhD) determinations and the unexpected antibodies were found in the appropriate microtube location in all duplicate sets of results. We conclude that the device accurately and reproducibly dispenses cells, sera and reagents. The savings of technologists' time over traditional manual tube methods exceed 75%, excluding the time to perform elements common to both methods. The combination of automation and microtube technology offers the opportunity for substantial savings in technologist time with accuracy in reagent and specimen dispensing.
