title: [Reproducibility of differential bronchoalveolar lavage cytology in sarcoidosis in relation to elapsed time between bronchoalveolar lavage and sample processing].
abstract: The physiological saline solution that is usually employed for BAL is not suitable as a storage medium for BAL cells for any longer period of time: even when cooled to 4 degrees C, the lymphocyte component decreases significantly after a latency period of 24 hours. With respect to the differential cytology performed on BAL fluid, the tissue culture medium RPMI 1640 + 5% AB serum can be employed as a storage medium. But even with this medium, a very clear reduction in the total cell count in BAl is seen at 24 hours.
