Test to improve peanut allergy diagnosis
Date:3/20/2012

tients would simply need to visit a GP rather than require a referral to a specialist allergy clinic.

"Due to the long wait times for specialist's clinics, many clinicians are faced with the difficult task of having to assess the presence of food allergy based solely on a positive skin prick test or other available tests and must err on the side of caution and accept a diagnosis of 'possible' food allergy in these situations," Dr Allen said

"This approach can lead to over diagnosis of peanut allergy in the community and a potentially unnecessary burden on the health care system," she said.

Diagnosis of peanut allergy is relatively straightforward when there is an obvious history of clinical reaction to peanut ingestion. However, diagnosis can be more complicated in cases in which the clinical history is not clear or in children who have not yet been exposed to a food.

Researchers say the 'Arah2' twostep process can be used in children with high risk of food allergy, such as those with eczema and other food allergies and for those who haven't eaten peanuts but have a strong family history of food allergy.
