The measurement of the nitric oxide concentration in the rectum or in a gas sample taken from the rectum of a patient can be used as a rapid screening method and as an aid in the diagnosis of allergies and intolerance reactions. A measurement performed after a rectal provocation with a suspected allergen or intolerance causing agent will give an indication as to the sensitivity to that specific allergen or agent. In nitric oxide measurements, without prior provocation, elevated levels compared to normal levels, obtained form healthy controls, are taken as an indication of allergy or a predisposition for allergy. One or several repeated measurements after elimination of the suspected allergen from the patient's diet can be used to confirm the diagnose and to check patient compliance. |
