• Digestive symptoms: bloating, gas, abdominal discomfort or diarrhoea that may relate to food intake.
• Skin and inflammatory symptoms: eczema, urticaria, rashes or inflammatory skin changes.
• Respiratory or ear-nose-throat symptoms: sinusitis, asthma or recurring ear infections.
• Headaches or migraines: patterns that appear linked with specific foods or eating habits.
• Joint or musculoskeletal concerns: arthritis symptoms monitored in relation to diet.
• Behavioural or mood considerations: mood fluctuations, irritability or behavioural changes potentially linked with foods.
• Nutrient absorption or gastrointestinal conditions: colitis or practitioner-monitored absorption concerns.
• Clients with chronic or recurring symptoms: those exploring whether delayed food reactivity plays a role in persistent issues.
• Family history or genetic predisposition: interest in food-related immune tendencies within families.
• Dietary review for rotation or elimination approaches: clients exploring structured diet strategies under practitioner guidance.

Overview

The IgG Food Antibodies test measures IgG responses to 87 individual foods alongside total IgE using an ELISA method. This combination offers practitioners an overview of both delayed IgG-mediated reactivity and overall IgE reactivity within a single serum assessment.

Clinically, this profile may be useful when exploring digestive symptoms, skin presentations, headaches or migraines, respiratory or ENT concerns, mood or behavioural changes, or musculoskeletal discomfort that appears to correlate with eating patterns. Evaluating IgG responses across a broad panel of foods may help practitioners consider whether delayed immune reactivity could be relevant within the wider clinical picture, while total IgE provides context around immediate-type sensitivity tendencies.

Practitioners generally interpret these findings alongside dietary intake, symptom history, lifestyle factors, digestive health, family tendencies and any structured elimination or rotation approaches under consideration. Used in this context, the IgG Food Antibodies test can help guide practitioner discussions about food-related patterns and support broader assessment and planning for clients.
