When is food intolerance testing worth doing?
Where it can help
Long-standing gut or skin symptoms — where your GP’s tests have excluded coeliac disease, inflammatory bowel disease and allergy, a diary has not settled the question, and you want a starting point for a structured rechallenge.
A diet that has already narrowed — where foods have been cut on a hunch and the job is to bring them back in properly and in order.
Deciding what to challenge first — as one input beside your history, your diary and your GP’s results, never as the answer on its own.
Where it does not help
Suspected allergy — hives, swelling, wheeze or vomiting soon after a food is a matter for your GP or allergist, and an intolerance test is not the way to find out.
Children with suspected reactions — tested and managed through their GP, allergist or paediatrician; we do not remove foods from a child’s diet on a test result.
As a routine — many plans need no testing at all. Testing is a decision we make together, after the first appointment, when a result would change what we do.
What stays with your doctor — allergy testing, coeliac testing before gluten is removed, action plans, and any severe reaction.
