Food intolerance testing at Metropolis: what to know

Food intolerance is a digestive response to a food or ingredient, and symptoms may include bloating, cramps, gas or diarrhoea. Different services use different samples and methods, so the name of a laboratory does not tell you what the test validates. Read the test description and ask how a finding relates to your personal symptoms.

A positive report is not a reason to remove every named food. Symptoms can have several causes, and overly narrow eating can affect nourishment. A clinician may use your history, examination and targeted tests to decide whether an intolerance is plausible.

Before sampling, write down meals, symptom timing, bowel changes, medicines and any food you already avoid. Ask whether normal eating is needed beforehand. If an intolerance is suspected, a clinician or dietitian may recommend removing one suspected trigger for a defined period and then reintroducing it to check whether symptoms return. Nutrition counselling can protect dietary variety while you work toward improvement.

Seek medical advice for diarrhoea that continues, recurrent bloating with pain, dehydration, black or bloody stool, fever, repeated vomiting or unplanned weight loss. Emergency care is needed for sudden breathing trouble, throat or tongue swelling, collapse or a rapidly spreading reaction after eating.

Ask what the sample detects, how the result changes care, whether another condition should be checked, and how to reintroduce foods safely if an elimination trial is recommended.
