Cerebrospinal fluid (CSF) cell count with differential is done to analyze the cellular components, number, and types of cells distributed in the CSF to obtain diagnostic information about various neurological conditions such as meningitis, encephalitis, and tumors. The total number of CSF cells counted on the stained slide is studied. An elevated count with differential cells gives insight into the type of infection.
