What your results can mean
Reading your report
IgG to foods is often found in healthy people, so discuss your result with your doctor before changing your diet.
If the result is outside the usual range
Raised IgG to a food is common in healthy people and often just reflects that you eat that food. It does not reliably show intolerance, which is why major allergy bodies do not recommend this test for diagnosis.
Who usually has this test
People with bloating, tummy pain or other symptoms they link to food, after discussing with a doctor whether the test is helpful.
Risks and aftercare
Do not cut out foods based on this result alone without speaking to your doctor or a dietitian.

Questions about this test
Is a food intolerance test the same as a food allergy test?
No. Allergy tests look for IgE antibodies, which are linked with allergic reactions. Intolerance panels measure IgG, which is not a reliable sign of intolerance.
Why do allergy experts not recommend IgG food testing?
IgG to foods is seen in most people and usually reflects normal exposure. Studies have not shown it diagnoses intolerance.
What is a better way to find foods that upset me?
A food and symptom diary and a supervised elimination diet with a doctor or dietitian are common approaches.
