Correct answer: B. B12 malabsroption

  • A. Folic acid level
  • B. B12 malabsroption
  • C. Pancreatic enzyme deficiency
  • D. Coronary artery disease

Explanation

The Schilling test was designed to assess vitamin B12 absorption by measuring urinary excretion of radiolabelled B12, sometimes with intrinsic factor. It therefore helps investigate B12 malabsorption rather than folate deficiency.
