This paper presents a review of 3 cases of glycosuria, which we have recently had the opportunity to study, in which the sugar content of the blood was normal. It was our feeling that attention should be called to the necessity of a complete investigation of all cases of glycosuria before the institution of the rigid management required by the diagnosis of diabetes mellitus. The social and financial implications of this disease are well realized even by one not in frequent contact with diabetic patients, and for these reasons alone the diagnosis should be made only after the most careful study and the accuracy of the diagnosis should be suspected if after a sufficient trial careful management is unsuccessful.
Of the nondiabetic glycosurias, that due to a lowered renal threshold for dextrose is the most common; the others, such as pentosuria, lactosuria, fructosuria and galactosuria, will be referred to only
