[Methods of cytological analysis of cerebrospinal fluid: development, problems, present state]

The authors present the basic methods of CSF sediment preparation and problems arising from methodological procedures. The results of widely used methods of "accelerated" sedimentation and cytocentrifugation are compared. The latter method was estimated as more effective because of the high cell yield as well as due to the result of cell differentiation reflecting the in vivo condition, especially with respect to lymphocyte and monocyte percentage.
