Efficiency of various methods of identifying cerebrospinal fluid in oto- and rhinorrhea.

This paper describes methods of cerebrospinal fluid (CSF) leakage diagnosis which have been used in the post-war period. We have listed advantages and disadvantages and given our opinion as to the value of each method. In the form of comparison we have provided a detailed breakdown of the exact procedure of beta 2-transferrin identification used for the immunological diagnosis of CSF leakage. This method, which was developed further by us, is discussed with regard to the results of all sample analysis which have been carried out so far. The result of the discussion is to emphasize the many advantages of this method. In addition, there is a direct comparison made between the fluorescein method and the use of beta 2-transferrin.
