Perceived allergy is much greater with 20 to 30% of people altering diets on the perception of food allergy (2,3). While there are hypotheses, the true mechanisms that drive tolerance and allergy remain elusive (4,5). As such, there is a growing need for improved diagnostics to clarify childhood food allergy and improve patient safety, concurrently decreasing the demand on limited public resources. This study will build on our recent work, which - for the first time - demonstrated the usefulness of non-invasive exhaled nitric oxide testing in reducing both cost and risk in the clinical diagnosis of peanut allergy, and expand its suitability to the most common food allergy in Australian children egg allergy.
Six to eight percent of children suffer from clinically relevant food allergy and the prevalence is increasing worldwide(1-3).
