Which laboratory finding is expected in vitamin-D-deficiency osteomalacia?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

B. Raised alkaline phosphatase with low vitamin D

Osteomalacia from vitamin D deficiency impairs mineralization and often causes low vitamin D with elevated alkaline phosphatase from increased osteoblastic activity.

Option by option

  • A. Normal vitamin D with high ferritin

    Normal vitamin D does not support deficiency osteomalacia.

  • B. Raised alkaline phosphatase with low vitamin D (correct)

    Correct: high ALP accompanies defective mineralization.

  • C. High troponin with low calcium only

    Troponin is a cardiac injury marker.

  • D. Elevated amylase only

    Amylase reflects pancreatic or salivary disease.
