Swan Science — Food Intolerance Test

Eliminate Uncertainty from Your Diet

Identify Your Ideal Diet with Confidence

Our test measures four subtypes of food-specific IgG antibodies (IgG1–4), providing a detailed picture of your immune system's antibody responses to different foods. These results reflect antibody reactivity and do not, on their own, diagnose food intolerance.

Consider the Bigger Picture

Digestive symptoms can have many different causes. Food-specific IgG antibody levels do not reliably identify which foods are responsible for symptoms. If you're experiencing ongoing digestive problems, a GP or registered dietitian can help you investigate possible causes and consider appropriate next steps.

Understand Your Results

Your report presents the IgG antibody reactivity measured against the foods included in the test, using an easy-to-read traffic light format. These results do not diagnose food intolerance and should not be used alone to decide which foods to remove from your diet.

My gut health journey!

"I struggled with constant stomach upset and pain for over a year. This test revealed I was intolerant to dairy, wheat, and even yeast! Cutting back on these changed everything—I finally felt relief. Thank you, Susan, for the recommendation!"

H. Guerrini, Curator of Rabbit Hole (formerly at Glastonbury)
