title: Cerebrospinal fluid.
abstract: It is hoped that we have demonstrated that collection, handling, and limited analysis of CSF samples from the dog and cat are relatively simple. No special equipment or handling is required, and the procedures are within the capabilities of any veterinarian interested in performing them. In addition, although this article was not intended to present a detailed discussion on the interpretation of the analysis of CSF, we have demonstrated some very practical interpretations to the various aspects of a routine CSF analysis. When combined with a signalment, complete history, and thorough general physical and neurologic examination, CSF analysis can prove invaluable in the workup of an animal with a neurologic disorder. Relatively simple laboratory procedures can be helpful in differentiating peripheral blood contamination from true intrathecal hemorrhage, in identifying an active inflammatory process, in potentially characterizing an etiologic agent, and, on rare occasions, in identifying primary or metastatic neoplastic disease involving the CNS. In many cases, the above is not directly possible, because the changes observed in our routine analysis are nonspecific. Yet, documenting and following these "nonspecific" alterations are helpful in determining if there is progression or regression of the disease process. In turn, these changes or lack of changes are helpful in identifying if the proper therapy has been instituted and if additional or different therapy is required.
