The definitive test in allergy is exposure to the food or medicine that is suspected of causing an allergy. As long as it is done correctly, in the right setting, by trained professionals, this is a safe procedure. Sometimes, this test is required to establish if an allergy has been outgrown or when the history and allergy tests are not in agreement. We are able to offer both high and low risk food and drug provocation challenges. The process involved will be fully explained if this is required.
