ABSTRACT
Objective To assess the whether the performance parameters of MEK‐7222K hematology analyzer conforming to the related requirements and applying in clinic .Methods MEK‐7222K hematology analyzer was used as the target analyzer .The blank test ,intra‐batch and inter‐batch precision test ,carryover rate test and linear verification were respectively performed .The whole blood WBC count detection results were compared between the MEK‐7222K hematology analyzer and the microscopic manual count for evaluating the accuracy of instrument measurement .Results The MEK‐7222K hematology analyzer met the requirements in the blank value ,intra‐batch precision ,inter‐batch precision and carryover rate ;the linear validation was passed ;the qualification rate of WBC classification met the accuracy requirement of WBC classification count .Conclusion The various performance parameters of the M EK‐7222K hematology analyzer meet the requirements and can be used in clinic .
