Abstract
The glucose content in cerebrospinal fluid was determined on samples from 29 normal subjects. The determination was performed by both a copper reduction method and a hexokinase method, and results were compared with glucose values in serum from blood samples drawn simultaneously. The glucose values by the enzymatic method were 4.5% less than by the reduction method. The cerebrospinal fluid to serum glucose ratio was approximately 70% by either method, and although there appeared to be considerable correlation between levels of glucose in serum and cerebrospinal fluid, the serum level does not appear to be the sole determinant of cerebrospinal fluid glucose levels.Keywords
