Evaluation of the QBC Star centrifugal three-part differential haematology system. Br J Biomed Sci. 2013;70(2):67-74 Authors: Erhabor O, Richardson G, Mohammed I, Thornton C, Bark J, Hurst M, Hamer D, Kinsella P Abstract The QBC Star haematology system includes the QBC Star centrifugal analytical analyser and the QBC Star tube system. Together, they are capable of producing a haematology profile on venous or capillary whole blood. The aim of this study is to compare full blood count (FBC) including differential white cell count performance between the QBC Star analyser and a gold standard Sysmex XE-2100 haematology analyser. The FBC performance was evaluated according to the National Committee for Clinical Laboratory Standards (NCCLS) document H20-A. Imprecision, correlation and linearity studies all showed excellent results. Overall, the haemoglobin, haematocrit, white cell count (WCC) and platelet count parameters showed excellent correlation. Mean corpuscular haemoglobin concentration (MCHC) results showed poor comparability. The white cell differential parameters showed good correlation within certain clinically significant limits. Imprecision for haemoglobin, haematocrit, WCC, MCHC and platelet count was considered acceptable. The re-read function was found to be stable over the five-hour testing period under the authors' laboratory environmental conditions. The subjective assessment by biomedical scientist staff demonstrated th...
