Compared to cytocentrifugation, microscope slide smear preparations had significantly higher percentages of lymphocytes. The microscope slide smears for the samples with predetermined numbers of cells yielded lymphocyte and neutrophil percentages which did not differ from the calculated differentials (59.6 +/- 1.5 vs 59.6 +/- 5.2% and 54.6 +/- 6.0 vs 53.1 +/- 6.0%, respectively). Varying the number of cells counted from 100 to 800 confirmed the reproducibility of the counts for counting 600 cells. Using 5 x 10(5), 2.5 x 10(5), or 1 x 10(5) cells per preparation demonstrated that adequate specimens could be obtained from as few as 1 x 10(5) cells. Thus, microscope slide smear preparation is a simple and accurate method for the quantitation of bronchoalveolar lavage fluid cytology. ER -
