Glucose oxidase test strips were used to evaluate the presence of glucose in nasal secretions and tears in a group of normal children. Substantial amounts of glucose were present in 15 of 17 samples of nasal discharge and 10 of 15 samples of tears. The use of glucose oxidase test strips for diagnosis of cerebrospinal fluid rhinorrhea, therefore, is without merit.
