Wimpole Street, Marylebone
People looking into allergy testing and inflammation marker in Marylebone are usually looking for the Histamine (Urine). It belongs to our food intolerance and digestive sensitivity group and needs a random urine sample, which a nurse or phlebotomist collects at 22 Wimpole Street, Marylebone once the clinic opens on 1 October 2026. The laboratory typically returns a result in 5 days, and the standard price is £158 with no members’ tier.

What Histamine (Urine) measures
Histamine (Urine) is most often requested in connection with allergy testing, inflammation marker and mast cells, which is why it sits within the food intolerance and digestive sensitivity group at Wimpole Street.
Food intolerance tests in the catalogue measure mechanisms other than IgE allergy: the lactose intolerance gene test identifies the common variant that switches lactase off in adulthood, diamine oxidase (DAO) activity estimates how well histamine from food is broken down, and histamine itself can be measured in urine. Gluten sensitivity evaluations combine coeliac serology with related nutritional markers for people whose symptoms do not fit classic coeliac disease. These tests address digestive and metabolic reactions rather than immune allergy.
Who considers Histamine (Urine)
- People often consider these tests if they get bloating, cramps or loose stools an hour or two after milk, cheese or ice cream.
- Flushing, headaches, nasal congestion or hives after red wine, aged cheese or cured meats sometimes lead to a DAO or histamine test.
- Those who feel better off gluten but have tested negative for coeliac disease may want a fuller evaluation.
- Anyone about to embark on a restrictive elimination diet may prefer to gather objective information first.
- Long-standing irritable bowel symptoms without a clear pattern are a frequent reason to explore intolerance.
Preparing for your Histamine (Urine)
- 1No fasting is needed for the lactose gene test; it is not affected by diet.
- 2For DAO activity, avoid alcohol and antihistamines for 24 hours, and note any DAO supplements you take.
- 3Keep eating gluten for six weeks if coeliac serology forms part of the profile.
Sample for this test: random urine sample.
Understanding your Histamine (Urine) results
Carrying the lactase non-persistence genotype can indicate a predisposition to lactose intolerance, though many carriers tolerate moderate amounts of dairy and the result is not a measure of current symptoms. A low DAO activity may suggest reduced capacity to clear dietary histamine, which is one possible contributor to food-related symptoms but not a validated diagnosis on its own. Gluten sensitivity profiles are interpreted mainly to exclude coeliac disease and nutritional deficiency; there is no blood test that confirms non-coeliac gluten sensitivity.
Intolerance tests provide supporting information for a structured dietary approach and are not a substitute for supervised elimination and reintroduction with a dietitian.
