ABSTRACT
Objective To verify the main index of Sysmex XN-1000 hematology analyzer and check whether performance of XN-1000 hematology analyzer meet the quality requirement.Methods The background value,carryover rate,precision,line-arity,reportable range,accuracy and comparability of different modes of sample absorbing of Sysmex XN-1000 hematology analyzer were verified and WS/T 406-2012 Analytical Quality Specifications for Routine Tests in Clinical Hematology was referred.Results The background counts,carryover rate,inter-batch precision and inter-day precision all met the require-ment.Linearity verification of WBC,RBC,HGB and PLT all met the requirement of the value of a within 1±0.05 and the correlation r≥0.975.The reportable range surpassed the range stated by the manufacture,which was accepted as the clinic reportable range.The accuracy test showed the mean and bias all met the requirement.The difference between the values de-tected by different absorbing modes all met the comparability requirement.Conclusion Performance of Sysmex XN-1000 he-matology analyzer was verified to meet the requirement.
