Abstract

Abstract:

Objective To evaluate the roles of automated image analysis system and CytoDiff flow cytometry for the diagnosis and treatment of leucopenia. Methodse A total of 181 patients with white blood cell count（0.5-2.0）×10⁹/L were enrolled and determined for differentiation and count by automated image analysis system and CytoDiff flow cytometry. Time,precision,correlation of blasts,sensitivity and specificity were compared with microscopy（standard method）. Results The median times were 864,277,190 and 364 s by microscopy,CytoDiff flow cytometry,DM96 preclassification and DM96 reclassification,respectively. The variation of CytoDiff flow cytometry for neutrophils,lymphocytes,monocytes and blasts was better than those of the other 3 methods. The correlation coefficients（r） between CytoDiff flow cytometry,DM96 preclassification,DM96 reclassification and microscopy were 0.937,0.507 and 0.990,respectively. The sensitivity and specificity of CytoDiff flow cytometry were 94.90% and 98.80%,respectively. The sensitivities of DM96 preclassification and DM96 reclassification were 54.08% and 79.59%,and the specificities were 74.69% and 100.00%,respectively. Conclusions DM96 reclassification and CytoDiff flow cytometry can detect blasts in leucopenia samples with high efficiency and accuracy and meet the demand of clinic for the curative effect monitoring and prognostic analysis.
