Presence of which of the following conditions in urine are indicative of diabetes mellitus?

Answer: (A) Ketonuria and Glycosuria. Answer: (A) Ketonuria and Glycosuria.

  1. A.Ketonuria and Glycosuria✓
  2. B.Renal calculi and Hyperglycaemia
  3. C.Uremia and ketonuria
  4. D.Uremia and Renal calculi

Correct Answer

(A) Ketonuria and Glycosuria

Solution & Explanation

Answer: (A) Ketonuria and Glycosuria. Solution: In diabetes mellitus, blood glucose is high, so glucose appears in the urine (Glycosuria), and the impaired use of glucose leads to ketone bodies appearing in urine (Ketonuria). NCERT specifically lists glycosuria and ketonuria as indicators of diabetes mellitus on urine analysis. Renal calculi, uremia and hyperglycaemia are not the urine-based diagnostic pair NCERT cites for diabetes mellitus, so options (B), (C) and (D) are incorrect. NCERT Reference: Ch 16, p.213, line(s) 12-14 — "presence of glucose (Glycosuria) and ketone bodies (Ketonuria) in urine are indicative of diabetes mellitus."
