This is an iatroX educational summary of named Canada sources, not an official guideline. It does not replace the complete source documents, local policy, specialist advice or clinical judgement. Alberta is used as an explicit Canadian implementation example, not as a national rule. Verify the equivalent pathway, formulary and escalation route in the patient鈥檚 province or territory.

Alberta source: bounded use

Provincial Celiac Disease Primary Care Pathway supplies a Canadian implementation example for this summary. It must not be presented as the rule outside Alberta.

Source-attributed clinical priorities

  • Test with appropriate serology while the patient is eating gluten and measure total immunoglobulin A or use an alternative assay when needed.
  • Confirm the diagnosis through the Canadian gastroenterology pathway before recommending a lifelong gluten-free diet.
  • Assess nutritional deficiency, bone health and associated autoimmune disease and arrange dietitian-supported follow-up.
  • Do not start a gluten-free diet before diagnostic testing because serology and histology may normalize.

Practical assessment and management workflow

1
Record diarrhea, weight, anemia, bone, neurologic, dermatitis and family or autoimmune history.
2
Order tissue-transglutaminase IgA with total IgA while the patient consumes gluten.
3
Use alternate serology for IgA deficiency and refer for confirmatory gastroenterology assessment.
4
After diagnosis, involve a dietitian and monitor symptoms, serology, deficiencies and bone health.

Safety, red flags and urgent escalation

  • Severe malnutrition, dehydration or major electrolyte disturbance needs urgent management.
  • Persistent symptoms despite adherence require review for ongoing gluten exposure, refractory disease or another diagnosis.
  • Screen first-degree relatives and associated autoimmune disease according to the Canadian pathway.
