Vitamin D test request protocol

Introduced May 2010

Vitamin D testing is performed for the following clinical indications

  • Unexplained raised serum alkaline phosphatase or low calcium or phosphate
  • Atypical osteoporosis
  • Unexplained proximal limb pain in older people
  • Unexplained bone pain, unusual fractures or other evidence suggesting metabolic bone disease in both adults and children (consider specialist advice for people in this category)
  • Patients in whom there are other good clinical reasons to suspect severe vitamin D deficiency. For example:
    • Patients with cystic fibrosis, malabsorption, or dark skin with other risk factors
    • Some patients with primary hyperparathyroidism
    • Patients on long term medications that may affect bone health or vitamin D levels, such as steroids or anticonvulsants
  • Strong clinical suspicion of vitamin D toxicity
