Acting to maintain the level of glucose in the body.
An abnormal amount of glucose in the urine. Traces of sugar, particularly glucose, may occur in normal urine but are not detected by ordinary qualitative methods. The presence of a reducing sugar found during routine urinalysis is suggestive but not diagnostic of diabetes mellitus. It is found when the blood glucose level exceeds the renal threshold (about 170 mg/dl of blood). The fasting level of blood glucose is normally between 70 and 99 mg/dl of blood.
