Allergy Tests
Allergy tests are medical assessments performed to determine if your symptoms are triggered by specific allergens. These allergens can range from certain foods, types of pollen, pet dander, dust mites and many others.
You may require an allergy test if they are experiencing symptoms such as hives, redness, itchiness, swelling or difficulty breathing that are often related to an allergic reaction. The aim of these tests is to pinpoint the allergen causing these symptoms, ultimately leading to better management of the allergy.
Types of allergy tests
Prick test
A skin prick/puncture test checks for immediate allergic reactions to as many as 40 or more different substances such as allergy to pollen, dust, pet dander, and foods at once.
- Uses plastic devices that barely penetrate the skin's surface. In adults, the test is usually done on the forearm. Children may be tested on the upper back.
- Small marks are drawn on your skin and a drop of allergen extract applied next to each mark. Within 15 to 20 minutes, your skin is observed for signs of allergic reactions.
- If you have allergies, just a little swelling that looks and feels like a mosquito bite will occur at the site where the allergen(s) to which you are allergic was introduced.
- The small hives where the tests were done, which will typically go away within 30 to 60 minutes.
Skin patch test
Patch testing is generally done to see whether a particular substance is causing allergic skin irritation (contact dermatitis). During a patch test, your skin may be exposed to 30 or more extracts of substances that can cause contact dermatitis. These can include latex, medications, fragrances, preservatives, hair dyes, metals and resins.
- Patch tests can detect delayed allergic reactions, which can take several days to develop.
- Allergens are applied to patches, which are then placed on your skin. You wear the patches on your arm or back for 48 hours.
- The patches are removed when you return to your doctor's office. Irritated skin at the patch site may indicate an allergy.
Skin injection test
When the results of your skin prick/puncture test are not clear, you may need a test that uses a very thin needle to inject a small amount of allergen extract just into the skin on your arm (intradermal test).
- The injection site is examined after about 15 minutes for signs of an allergic reaction.
- Your doctor may recommend this test, especially to check for an allergy to insect venom or penicillin.
Challenge test
A very small amount of a substance is injected or taken by mouth. Challenges are done mostly with potential food or medication allergies, and for diagnosing asthma.
Blood tests
Blood tests are generally used when skin tests might be unsafe or won’t work, such as if you are taking certain medications, or have a skin condition that may interfere with skin testing.
