Which of the following analytes would not commonly be measured when monitoring complications of diabetes mellitus?

• A. Serum urea nitrogen
• B. Urinary albumin
• C. Serum creatinine
• D. Serum bilirubin

Answer: (D)

The key idea is that monitoring diabetes complications mainly targets kidney involvement, since diabetic nephropathy is a common and serious microvascular complication. Urinary albumin is used to detect early kidney damage from diabetes, and serum creatinine and BUN (urea nitrogen) reflect kidney function and the degree of renal impairment. Serum bilirubin, on the other hand, is a marker of liver function and conditions affecting bilirubin metabolism or red blood cells, not a typical marker for diabetes-related complications. So bilirubin isn’t commonly part of monitoring diabetes complications, making it the best answer.
