To analyze the reliability and comparability of different hematology analyzers and to standardize the operation of a contrast test. Methods The carryover rate, precision, total precision and percentage of differences of hematological analyzers were evaluated and differences of items in whole blood were compared by detecting 20 anticoagulant fresh blood samples based on the documents of ICSH and NCCLS. Every 3 blood samples of highvalue, middlevalue and lowvalue were detected by hematological analyzers everyday for 7 days.
