• Gluten-related symptoms: Bloating, abdominal discomfort, diarrhoea or other symptoms where gluten sensitivity is being considered.
• Unclear food-related reactions: Assessment when symptoms appear linked to gluten-containing foods but patterns are inconsistent.
• Chronic digestive symptoms: Ongoing gut symptoms where gluten-related mucosal immune activity may be relevant.
• Mucosal immune assessment: Further evaluation where secretory IgA status may add useful clinical information.
• Follow-up of gluten avoidance: Reassessment in individuals reducing or avoiding gluten.
• Further dietary investigation: When symptoms persist and gluten remains part of the clinical picture.

Overview

The Gliadin Sensitivity Profile is a non-invasive test that measures salivary anti-gliadin IgA and secretory IgA. Together these markers provide information about immune reactivity to gliadin, a protein component of gluten, and mucosal immune activity.

Abnormal findings may help provide context in individuals with digestive symptoms or suspected gluten sensitivity, particularly where a mucosal immune response is being considered. Measuring secretory IgA alongside anti-gliadin antibodies can add useful clinical detail when symptoms appear food-related but are not straightforward.

Results are interpreted alongside symptom history, diet history and other relevant investigations where appropriate. The test may be useful for further dietary assessment or follow-up in individuals with ongoing gluten-related concerns.
