Skin prick allergy test
Selected allergens are applied to the forearm or the back with a dropper, and the skin gently pricked with a sterile lancet. A positive result shows as a red weal or flare on the skin within 20 minutes. This test is usually done in order to identify allergies to pet dander, dust, pollen, foods or dust mites. If an immuno-response is seen in the form of a rash, urticaria (hives), or (worse) anaphylaxis it can be concluded that the patient has a hypersensitivity (or allergy) to that allergen. Further testing can be done to identify the particular allergen.
