European multi-center evaluation of the Abbott Cell-Dyn sapphire hematology analyzer.

This study presents the results of performance evaluations of the Cell-Dyn Sapphire (CD-Sapphire) undertaken by 3 study sites in Europe. These studies focused on the routine blood count analyses with specific consideration of precision and imprecision, linearity, inter-instrument correlations, and white blood cell differential and flagging efficiencies. The CD-Sapphire was compared to the Cell-Dyn CD4000, Bayer Advia 120, Beckman Coulter GenS, and reference microscopy.
