Abstract
The appearance of glucose in urine depends on 3 factors: the blood sugar level, the filtration rate, and the renal threshold of glucose. The tubular reabsorption of glucose was examined by simultaneous detn. of the endogenous creatinine clearance or the inulin clearance, the glucose excretion and the blood sugar level in 4 normal subjects, in 4 cases of renal diabetes, in 12 cases of diabetes mellitus, and in 2 cases of kidney disease. The results of these various conditions were discussed.
