BAL fluid recovery and cellular composition in lung transplant recipients (LTR) with and without bronchiolitis obliterans syndrome (BOS) and normal controls
| BAL return (ml) | TCC (×104/ml) | AM (%) | Lym (%) | Neu (%) | Eos (%) | Ep (%) | |
| LTR with BOS (n = 7) | 63 (22)2-165 2-151 | 55 (69) | 36 (19)2-165 2-164 | 17 (12) | 42 (27)2-165 2-164 | 0.8 (0.6) | 4.0 (3.1) |
| LTR without BOS (n = 19) | 86 (11)2-165 | 16 (5) | 73 (8) | 19 (9) | 4.7 (2.2)2-160 | 0.3 (0.2) | 2.8 (1.6) |

Values are mean (95% CI).
TCC = BAL fluid total cell count; AM = alveolar macrophages; Lym = lymphocytes; Neu = neutrophils; Eos = eosinophils; Ep = epithelial cells.
