> Recommends against routine 25(OH)D testing in the general population aged 50 to 74 years. Triggered when a clinician considers ordering 25(OH)D for asymptomatic adults aged 50-74 without established indications such as hypocalcemia, malabsorption, or chronic kidney disease.

# Against routine 25(OH)D testing in adults 50-74

## STEP 1 — Gather Information
Collect patient age, presence of symptoms suggestive of vitamin D deficiency (e.g., bone pain, proximal myopathy), history of conditions that alter vitamin D metabolism (e.g., CKD, malabsorption, bariatric surgery, medications causing catabolism), and current supplement/diet intake.

## STEP 2 — Rule In / Rule Out
Is the patient aged 50-74 years, asymptomatic, and lacking established indications for 25(OH)D testing? If yes, proceed to Step 3. If no (outside age range, symptomatic, or has established indication), consider testing per other indications.

## STEP 3 — Classify or Stratify
Classify the request as routine screening (no indication) versus indicated testing. For routine screening in this age group, the recommendation is against testing.

## STEP 4 — Decide
Do not order a routine 25(OH)D test; instead, discuss that empiric vitamin D supplementation beyond dietary reference intakes is not recommended for this age group without established indications, and focus on adequate calcium intake and lifestyle.

## Clinical Guardrails / Mimics / Pitfalls
Do not use 25(OH)D levels to guide supplementation in asymptomatic adults 50-74; avoid testing in dark complexion, obesity, or pregnancy unless specific indications exist; recognize that testing may lead to unnecessary costs and potential over-treatment; do not apply this recommendation to individuals with malabsorption, CKD, osteoporosis, or other conditions affecting vitamin D metabolism.

## Concrete Clinical Example
A 62-year-old man with no bone pain, fractures, or gastrointestinal surgery requests a vitamin D level after reading about deficiency online. He takes a standard multivitamin. According to the guideline, advise against routine 25(OH)D testing; explain that empiric supplementation above DRI is not recommended and that maintaining adequate calcium and weight-bearing activity is sufficient.
