Would you expect to find glucose in urine if the blood supply in the kidney has a high level of glucose?

Yes, if the blood supply to the kidney has a high level of glucose, you might expect to find glucose in the urine, especially if the renal threshold for glucose reabsorption is exceeded. Under normal circumstances, the kidneys reabsorb most of the glucose from the filtrate back into the bloodstream. However, when blood glucose levels are significantly elevated, as in uncontrolled Diabetes, the kidneys may not be able to reabsorb all the glucose, leading to its presence in the urine.
