Cytocentrifugation of cerebrospinal fluid with dextran: improvement of the standard technique using the cytospin apparatus.

A method of processing cerebrospinal fluid (CSF) with a dextran solution admixture is described for use with the Cytospin apparatus. The method gave better results than the standard technique, and, compared with the CSF sedimentation method, it provided a reliable, although decreased, cell recovery and a higher quality of cell morphology.
