IgG food sensitivity panel
Widely sold, but IgG antibodies mostly show which foods you eat often - not which foods are causing symptoms.

Why we don’t recommend IgG food tests
IgG antibodies to foods are a normal sign you’ve eaten them - not of intolerance. Allergy societies advise against these tests, and cutting foods based on them can lead to needless restriction.
What it measures
“What do my results mean?”
IgG rises with exposure - often to the foods you eat most.
Exposure, not intolerance
The risk
“Should I cut these foods?”
Unneeded elimination can hurt nutrition and your relationship with food.
Caution
Better options
“What should I do instead?”
A symptom diary, celiac test, breath test or guided elimination diet.
Evidence-based
Is it right for you?
Worth considering if…
- There isn’t a clinical situation where it’s recommended for diagnosis.
A better option if…
- You react quickly to a food - see specific IgE or skin prick testing.
- You have bloating - consider celiac or breath testing and a food diary.
