Glycosuria (C0017979)

Definition (MSH)The appearance of an abnormally large amount of GLUCOSE in the urine, such as more than 500 mg/day in adults. It can be due to HYPERGLYCEMIA or genetic defects in renal reabsorption (RENAL GLYCOSURIA).
Definition (CSP)presence of glucose in the urine, especially the excretion of an abnormally large amount of sugar (glucose) in the urine.
