The NS-hema21t is a new, fully automated Egyptian hematology analyzer, designed to generate CBC with 3-part differential. The aim of our study was to perform a performance evaluation for this analyzer. Methods: Performance was evaluated according to CLSI EP15-A2, EP06 and ICSH guidelines. Beside precision, trueness, linearity and carry-over, a comparison study with the Sysmex XT1800i and a manual reference leukocyte differential was performed. Flagging performance was also evaluated. Results: NS-hema21t showed excellent precision, trueness, linearity and carry-over results for all parameters tested. Comparison studies showed an acceptable correlation with both Sysmex XT1800i and the manual reference leukocyte count. A suboptimal flagging performance was demonstrated. Conclusion: the global verification results obtained provide a satisfactory integration of the NS-hema21t in the laboratory routine and accomplish an optimal reliability.
