• Digestive symptoms: bloating, belching, abdominal pain or changes in bowel habits.
• Bowel pattern changes: diarrhoea, constipation or alternating stool patterns.
• Food-related reactions: suspected delayed responses following food intake.
• Skin concerns: rashes, hives or acne with possible dietary associations.
• Respiratory symptoms: congestion, wheezing or recurrent upper airway irritation.
• Neurological symptoms: headaches, dizziness or poor concentration.
• Energy changes: fatigue, lethargy or reduced stamina.
• Mood and behaviour changes: irritability, anxiety or low mood.
• Weight changes: unexplained weight gain, difficulty losing weight or being underweight.
• Joint and muscle discomfort: stiffness, aches or reduced mobility.
• Gluten-related concerns: digestive or systemic symptoms linked to gluten-containing foods.
• Recurrent symptoms: patterns that persist despite dietary or lifestyle adjustments.

Overview

The Immuno 1 IgG 115 + Gliadin test measures IgG antibodies to a broad panel of 115 commonly consumed foods together with IgG and IgA antibodies to gliadin. The test is performed using ELISA technology on a serum blood sample and provides information on immune antibody responses to foods and to the gluten-derived protein gliadin.

Clinically, this test may be useful when symptoms raise questions about delayed food-related immune responses or possible gluten-related reactivity. Reviewing antibody patterns across a wide range of foods and gliadin may help practitioners observe associations between dietary intake and digestive, skin, respiratory, neurological or energy-related symptoms.

Practitioners typically interpret results alongside dietary history, symptom patterns, lifestyle factors, medication use and other laboratory findings. When considered together, this information can support structured discussions with clients about dietary patterns, food exposure and potential next steps for dietary exploration.
