[Evaluation of an haematological analyser (Siemens Advia(®) 2120i) and improving quality of daily practice]. / Étude des performances analytiques d'un automate d'hématologie (Advia(®) 2120 i Siemens) et apport sur la pratique quotidienne.

A risk analysis, with method validation, and a study of the relevance of morphological alarms triggered by the automat have been made to the automat Advia(®) 2120i (Siemens). The analytical performance of the systems: repeatability, fidelity, contamination, linearity, correlation, the accuracy and approach to uncertainty, are compliant with the expected results (Ricos). Thanks to the retrospective study of morphological alarms triggered by the automat and based on the recommendations of the ISLH, a new attitude about blood smear was introduced. For platelets in citrate, a slight underestimation of the number compared to those collected in EDTA was observed probably need to redefine normal platelet values citrate.
