What does the term 'Glycosuria' indicate in medical diagnostics?
Answer and explanation
Correct answer: A. Excretion of glucose in the urine, typically when blood glucose exceeds renal threshold
- Step 1: The renal threshold for glucose in human kidneys is ~180 mg/dL (10 mmol/L). Step 2. When blood glucose exceeds this threshold, tubular transport max (TmG) is saturated, causing glucose to spill into urine (glycosuria). Answer: Excretion of glucose in the urine, typically when blood glucose exceeds renal threshold. Why not the others: Ketone accumulation is ketosis; Calcium excretion is hypercalciuria; Glycogen deficiency is glycogen depletion.
