Abstract:
Objective To investigate the examination of tumor cells in pleural effusion by body fluid mod-el of Sysmex XN-9000 automated hematology analyzer ,and set the cutoff value of HF-BF# and HB-FB%for screen-ing tumor cells in pleural effusion. Methods One hundred and six pleural effusion specimens were detected by Sysmex XN-9000,and malignant samples were confirmed by TCT(Thinprep Cytology Test)and immunohistochem-istry method. Results Of 106 specimens,44 cases of HF-BF count were positive,and 12 samples were confirmed malignant by TCT and immunohistochemistry method. The cutoff value of HF-BF#(× 106/L)and HF-BF%/100WBC were 3.5 and 1.55 respectively. The detection sensitivity,specificity,positive predictive value,negative predictive value,accuracy of HF-BF# were 66.7%,40.1%,27.3%,91.7% and 63.2% respectively and those of HF-BF%were 83.3%,40.6%,27.3%,91.7%and 63.2%respectively. Conclusions HF-BF# and HF-BF%of body fluid model of Sysmex XN automated hematology analyzer are effective for screening tumor cell in pleural effusion ,and all the screening samples must be confirmed by pathology methods.
