Laboratory evaluation of the Sysmex SE-9500 automated haematology analyser

Summary The Sysmex SE-9c500 is a new, fully automated haematology analyser, providing a complete blood count (CBC), including a five-part differential count (DC), with flagging of morphological abnormalities. The SE-9500 was evaluated according to guidelines published by the International Committee for Standardisation in Haematology (ICSH). The results demonstrated minimal carryover ( 0.995). Samples were stable with regard to CBC parameters after storage for up to 48 h at room temperature (RT) and 4 ∞C. Imprecision was generally acceptable for all CBC parameters (CV 0.97) for all the major CBC parameters (WBC, RBC, HGB, PLT). There was minimal interference for WBC, RBC, HGB and PLT at high concentrations of bilirubin (BILa 224 lmol/l) or triglyceride (TGa 7.78 mmol/l). SE-9500 reference values for CBC parameters are presented. Our results indicate that the SE-9500 is an excellent tool for routine haematological examination.
