What should you know about PRIME test food intolerance?

Food intolerance describes difficulty digesting or responding to a food without the immune emergency seen in anaphylaxis. Symptoms can include bloating, abdominal pain, gas, nausea, or diarrhoea, often after a particular food or ingredient. The pattern may be delayed and can depend on the amount eaten.

A test cannot by itself explain every digestive symptom. Food intolerance can overlap with irritable bowel syndrome, coeliac disease, lactose malabsorption, or food allergy, which requires a different assessment. A clinician may review your history and arrange targeted tests rather than relying on a broad home panel.

Keep a diary of foods, portions, timing, symptoms, bowel changes, medicines, and other possible triggers. Do not remove several food groups for a long period without professional guidance, because this can reduce nutritional variety and make the pattern harder to interpret.

Discuss the result with a doctor or dietitian before changing your diet. A supervised removal and reintroduction plan may help identify whether a food is responsible while protecting adequate nutrition. Nutrition counselling can be useful when symptoms persist or the diet becomes restricted.

Arrange medical review for ongoing diarrhoea, unexplained weight change, repeated vomiting, blood in the stool, nighttime symptoms, fever, or symptoms that interfere with daily life. Seek emergency help for facial or throat swelling, breathing difficulty, faintness, or rapidly spreading hives after eating, because these may indicate food allergy rather than intolerance.

Ask what the test actually measures, whether you need testing for coeliac disease or allergy, how long any elimination plan should last, and how to reintroduce foods safely. Bring your symptom diary and the full test report.
