Abstract:

Objective To verify the main performance of BD FACSCantoⅡflow cytometry analyzer. Methods According to the Clinical and Laboratory Standards Institute(CLSI)documents and projects provided from other literatures,the analytical performance of BD FACSCantoⅡflow cytometry analyzer was evaluated by precision,accuracy,linearity and reference range of common test items(peripheral blood lymphocyte subtypes:CD3+T cell,CD3+CD4+T cell,CD3+CD8+T cell,B cell and NK cell). The results were compared with the claims of manufacturers. Results The precision,accuracy,linearity and reference range of BD FACSCantoⅡflow cytometry analyzer in the determination of peripheral blood lymphocyte subtypes were in line with the performance parameters of manufacturers. Conclusions BD FACSCantoⅡflow cytometry analyzer has a good performance,accurate measurement and a high repeatability in the determination of peripheral blood lymphocyte subtypes,which can satisfy the need in clinics.
