Differential Cell Counts in sequential bronchoalveolar lavages performed in lung transplant recipients. Two sequential bronchoalveolar lavages (BALs) were performed in 6 consecutive lung transplant recipients and cell subtypes were manually counted. Differential cell counts demonstrate that BAL2 has a lower proportion of epithelial cells (p < 0.05) (a), a lower proportion of neutrophils (p < 0.05) (b), a trend towards greater proportion of macrophages (p = 0.06) (c), and a similar proportion of lymphocytes (p = 0.78) (d). A non-parametric Wilcoxon matched-pairs signed rank test was used for comparison.
