WebThe cells are applied to a glass slide by cytocentrifugation. Wright-Giemsa stained slides are examined by light microscopy and a differential is performed. Total nucleated cell count is determined using an automated hematology analyzer or a microscopic counting chamber.(Instruction manual: Automated Hematology Analyzer XN series [XN-1000]. WebAbstract. Manual microscopic cell counting in a Fuchs-Rosenthal (FR) chamber has been the gold standard for quantification of leukocytes in cerebrospinal fluid (CSF). However, for accurate determination of the number and differentiation of cells by chamber counting, hemocytometers must be prepared carefully and kept clean.
