Allergy testing is a crucial diagnostic tool that helps identify the specific allergens
responsible for triggering allergic reactions. By administering small doses of allergens to
patients, allergists can accurately pinpoint the culprits behind the reactions.This
information is invaluable in developing an effective allergy treatment plan.

There are two main types of allergy tests:
1. Skin Tests -There are multiple types of skin tests available to determine allergies. During the
first type of skin test, known as a skin prick test, a drop of a suspected allergen is pricked on the
surface of the skin.The test is performed on the back of the arm, most commonly the forearm.
Many suspected allergens are tested simultaneously. Redness and swelling occur at the test spot
if an allergic reaction occurs.
If the results from a skin prick test are unclear, a second type of test may be recommended to
rule out false positives. In this type, known as a skin injection test, a small amount of the
suspected allergen is injected into the skin of the arm or forearm. Several suspected allergens are
tested simultaneously.
2. Blood Tests – Blood tests can be used to determine allergies, although they can produce false
positives and are not considered as accurate as skin tests.
