# Endo Against 25ohd Test Healthy Adults

> The Endocrine Society guideline recommends against routine 25(OH)D testing in asymptomatic adults without established indications for vitamin D assessment. Trigger when a clinician considers ordering a 25(OH)D level for a healthy adult with no symptoms of deficiency and no clinical indications such as hypocalcemia, malabsorption, or osteoporosis.

# Against routine 25(OH)D testing in healthy adults

## STEP 1 — Gather Information
Collect patient age, symptoms (e.g., bone pain, fatigue), medical history for conditions affecting vitamin D (malabsorption, CKD, granulomatous diseases, osteoporosis, hypocalcemia), current supplements, and ask whether any established indication for 25(OH)D testing exists; end with a list of identified indications or confirmation of none.

## STEP 2 — Rule In / Rule Out
Is there an established indication for 25(OH)D testing (e.g., hypocalcemia, malabsorption, CKD, osteoporosis with fracture, granulomatous disease)? If yes, consider testing per other guidelines (outside this skill); if no, proceed to step 3.

## STEP 3 — Classify or Stratify
Does the patient have any condition that alters vitamin D physiology (e.g., chronic kidney disease, liver failure, malabsorption, granulomatous disorders, medications affecting vitamin D metabolism)? If yes, testing may be indicated per clinical context (outside this skill); if no, classify as a healthy adult without indication and proceed to step 4.

## STEP 4 — Decide
Recommend against routine 25(OH)D testing; discuss that empiric low-dose vitamin D supplementation may be considered only if aligned with other guideline recommendations (e.g., for specific age or risk groups) but should not be based on an unindicated test result.

## Clinical Guardrails / Mimics / Pitfalls
Do not order 25(OH)D solely for screening in asymptomatic adults; do not initiate vitamin D replacement based on low 25(OH)D without clinical indication; do not repeat 25(OH)D to monitor supplementation unless treating a defined deficiency; avoid interpreting low levels as deficiency in the absence of symptoms or related disorders.

## Concrete Clinical Example
A 45‑year‑old woman with mild fatigue requests a vitamin D level; she denies bone pain, fractures, GI symptoms, has normal calcium, no osteoporosis risk, and takes no medications affecting vitamin D. No established indication is found; per guideline, routine 25(OH)D testing is discouraged, and supplementation is not advised based solely on the request.
