Histamine Intolerance Test

Histamine Intolerance Test

Headache, tachycardia, abdominal pain, flatulence, rash and itching may be signs of histamine intolerance.

Histamine Intolerance is an intolerance of histamine consumed through food. It is caused by a deficiency of the histamine-degrading enzyme diamine oxidase (DAO) or an imbalance between histamine and DAO. As far as experts are concerned, it is not normally caused by genetic factors but is an acquired disease, often identified as a secondary condition to another.

Check your histamine tolerance easily and conveniently from home. The test is used to determin the concentration of diamine oxidase (DAO) in your blood. The histamine intolerance test includes free evaluation in the diagnostic laboratory and a detailed results report.

Symptoms of a histamine intolerance

  • gastrointestinal disorders
  • headaches
  • menstruation problems
  • asthma
  • nausea when travelling by car
  • cardiovascular problems

Histamine is responsible for the body’s defense against unwanted substances. An intolerance is a trigger for allergies and often occurs in people with a disturbed intestinal barrier. Histamine is a neurotransmitter and is degraded by the enzyme diamine oxidase (DAO). If the intestine is weakened or ill, the production of diamine oxidase may be too low.

Please note
that a relevant result is only guaranteed in case you eat a varied diet prior (approx 2 weeks) to the testing. Please don't avoid or reduce the consumption of food containing histamine. Please don't take antihistamines.
