• Digestive discomfort: bloating, gas, irregular bowel patterns or abdominal discomfort.
• Skin concerns: rashes, eczema, itching or other skin irritations.
• Headaches or migraines: recurring head pain potentially influenced by dietary triggers.
• Fatigue or low energy: fluctuations in energy that may coincide with food intake.
• Joint or muscle discomfort: aches or stiffness suspected to follow certain foods.
• Weight or appetite changes: shifts in hunger, cravings or weight management difficulties.
• Food-related reactions: experiences of delayed responses after eating specific foods.
• Mood or cognitive concerns: irritability, low mood or brain fog possibly linked with eating patterns.
• Nutrient absorption concerns: issues such as iron, B12 or folate insufficiency under practitioner review.
• Individuals with multiple or unclear food triggers: cases where a broad review of food reactions may be helpful.

Overview

The Food Panel 240 IgG test measures IgG antibody responses to 240 individual foods using ELISA methodology, offering a broad overview of delayed immune reactivity across multiple food groups. The dried blood spot or serum format provides quantitative results for each food, displayed as relative IgG levels.

Clinically, this assessment may be useful when exploring digestive discomfort, skin concerns, headaches, fatigue, joint symptoms or mood and cognitive changes that appear to correlate with eating patterns. Reviewing IgG patterns across a wide range of foods may help practitioners identify potential relationships between food intake and delayed immune reactivity. The broad panel can also be helpful when clients report multiple suspected triggers or inconsistent responses to different meals.

Practitioners typically interpret these findings within a wider context that includes dietary history, symptom timelines, lifestyle factors, digestive health, nutrient status and family tendencies. Used in this way, the Food Panel 240 IgG test can support structured dietary discussions, inform rotation or elimination strategies and contribute to an overall understanding of food-related patterns for clients.
