Food allergy is common, it can lead to significant morbidity andnegatively impacts on quality of life; therefore, it is vitally important we get the diagnosis right. However, making the diagnosis can be complex. Clinical history is the most important diagnostic tool and subsequent investigation may help confirm the diagnosis.

Within this article we explore the evidence related to targeted testing and how to interpret these within the clinical context.
