Hi there and thank you for your question!
The most commonly available food sensitivity test is the food IgG test. This test has not been scientifically proven to be accurate or reliable (1). The American Academy of Allergy, Asthma & Immunology, the Canadian Society of Allergy and Clinical Immunology and the European Academy of Allergy and Clinical Immunology have recommended against using IgG testing to diagnose food allergies or food intolerances / sensitivities.
If you are looking for proper advice, ask your doctor for a referral to see an allergist or immunologist who can help you properly diagnose and manage your condition.
I hope this helps! Check out our Lifestyle pages to help you improve other parts of your health.
