[Diagnosis of cerebrospinal fluid: the use of semiquantitative rapid tests. Investigation of the adsorbance of proteins to glass and plastic tubes (author's transl)].

The semiquantitative rapid tests used in the present study proved to be sufficiently sensitive for the estimation of erythrocytes in CSF samples, but they were inadequate with respect to the estimation of less than 100 microliter mononuclear and less than 10/microliter segmental neutrophilic leucocytes, of bilirubin, and albumin. Plastic tubes and cuvettes (e.g. of polystyrol) did not adsorb IgG, IgA, albumin or prealbumin from CSF samples, but adsorbed up to 80% of each purified single protein.
