Abstract:

Objective A comprehensive performance evaluation was done for dry-type blood cell analyzer(QBCRD) based on comparison with Sysmex XE-2100D Blood cell analysis system.Methods White blood cell, hemoglobin, platelet, hematocrit, granulocyte absolute count, lymphocyte absolute count, and monocyte absolute count were tested by QBCRD and Sysmex XE-2100D blood cell analysis system in double-blind trail. Precision of QBCRD was calculated, and also the linearity regression equation, paired T-test.Results CVs of the above 6 parameters were all less than 5%, showing a good precision. Good correlation with Sysmex XE-2100D blood cell analysis system in the above 6 parameters(r2: 0.99, 0.98, 0.98, 0.95, 0.99 and 0.96). There was no significant difference between QBCRD and Sysmex XE-2100D blood cell analysis system in the above 6 parameters based on P value of paired T-test are all above 0.05. Conclusion All the items evaluated in QBCRD were highly correlated with System XE-2100D automated blood cell analysis system. QBCRD dry method blood cell analyzer is suitable for field hospital of army or on-the-spot first aid.
