Against routine vitamin D testing in adults over 75
STEP 1 — Gather Information
Collect patient age, presence of symptoms or conditions that constitute established indications for 25(OH)D testing (e.g., hypocalcemia, osteoporosis, history of falls/fractures, malabsorption, chronic kidney disease, or current vitamin D supplementation therapy requiring monitoring).
STEP 2 — Rule In / Rule Out
If patient is <75 years old OR has any established indication for vitamin D testing → consider testing per other guidelines (rule out). If patient is ≥75 years old AND has no established indications for testing → proceed (rule in).
STEP 3 — Classify or Stratify
Classify as "No routine testing indicated" for all patients meeting rule‑in criteria; further stratification by risk factors (obesity, dark complexion, institutionalization) does not change the recommendation against routine screening.
STEP 4 — Decide
Do not order a routine 25(OH)D test; if vitamin D supplementation is desired per guideline recommendation 6, prescribe empiric low‑dose supplementation (e.g., 800–1000 IU daily) without prior testing.
Clinical Guardrails / Mimics / Pitfalls
Do not test solely based on age; do not delay empiric supplementation awaiting test results; do not interpret low 25(OH)D as deficiency in asymptomatic older adults without clinical correlates; avoid testing in patients with hypocalcemia, malabsorption, osteoporosis, or recent fractures—these are indications for testing, not screening.
Concrete Clinical Example
An 80‑year‑old woman with well‑controlled hypertension asks whether she should have a vitamin D level drawn. She reports no bone pain, falls, fractures, malabsorption, or hypocalcemia, and is not currently taking vitamin D. According to the guideline, routine testing is not recommended; instead, empiric vitamin D supplementation of 800–1000 IU daily may be considered if not already supplementing.
