Proposed evaluation of laboratory performance in an external hematology quality control scheme.
The commercial control material for hematology Cell Dyn 16 Tri Level gave a good precision an accuracy using the four blood cell counters currently mostly used in Indonesia, the Coulter, Sysmex, Serono and Cell Dyn. It could be used as one of the hematology control material in an external quality control scheme. Result of the CV from participating laboratories are higher compared to this trial are caused by different level of laboratory technical ability although the geographical area and climate may also play a role. The new scoring calculation to evaluate the participant's performance gave a more wider range of DI scores, to give better insight to the performance of each laboratory.
