Abstract

The present study was designed to evaluate the automated analysis of bone marrow aspirates with the CELL-DYN 4000 (CD4000) hematology analyzer. Bone marrow aspirates were diluted twice with phosphate-buffered saline and assayed with the CD4000. The percentages of subpopulations including lymphocytes, neutrophils, and erythroblasts were obtained with the CD4000, and as a reference, differential counts by microscopic observation of May-Grünwald-Giemsa-stained films of bone marrow aspirate were performed (n = 48). Significant correlations (p < 0.0001) between the results with the two methods were obtained for total nucleated cell count, lymphocytes, neutrophils, erythroid cells, and the myeloid/erythroid ratio. The present method can provide quantitative data of bone marrow aspirate and will be useful in bone marrow screening.
