Skin prick tests can be performed for inhalant allergens, foods and drugs. Intradermal is only performed for drugs. By introducing tiny amounts of the suspected allergens into or just under the skin, our Consultants can observe any reactions within just a few minutes. These reactions are caused by local histamine release at the site of the prick. If you are taking any anti-histamine medication, these should be stopped 3 days before  attending for skin prick testing, as they can affect the results.

​

For certain food allergies, you may be asked to bring along a sample of the item you think has been causing the reaction. The Consultants at the LAC can then prepare this sample for a skin test.
