Allergy skin tests are used to identify the environmental allergens that trigger allergic reactions. Tiny amounts of allergens are placed on your forearm, and a series of tiny scratches or needle pricks force the allergens into the skin. For an intradermal allergy test, tiny amounts of an allergen are injected just below the skin.
Allergy skin tests are safe, fast, accurate and relatively inexpensive. In most cases, they cause little pain or discomfort. After a patient’s allergy has been diagnosed, a physician will recommend a treatment plan to reduce or eliminate symptoms.
This test does not take very long, however, the respiratory therapist will have you wait 10 to 30 minutes to see if a local wheal, or hive, develops. If a positive skin reaction to that allergen is detected, an allergy is likely.
Please refrain from taking anti-histamines (e.g. Claritin, Reactine, Tylenol Sinus and Cold, some nasal sprays) five days prior to your test.
There is a $20 tray fee charged to patients who obtain an allergy skin test.
