80 Unit Skin Test
The area of the skin is observed for about 20 minutes to see if a reaction develops. The “wheal ”- a raised, red, itchy bump and surrounding “flare” – indicates the presence of the allergy antibody when the person is exposed to specific allergens.
The larger the wheal and flare, the greater the sensitivity.
Anywhere from 10 to 80 different allergens are tested. It takes about 5 to 10 minutes to place the allergens on your skin.
If you are sensitive to any of the allergens, your skin may itch where the allergen was placed.
How should I prepare for my test?
Tell your allergist about all medicines you’re taking, including over-the-counter medicines.
Do not take antihistamines for 3 to 7 days before the test. Ask your allergist when to stop taking them. (It’s okay to use nose (nasal) steroid sprays and asthma medicines. They will not interfere with skin tests.)
Allergy Testing Standards
Allergies occur when your immune system, which is your body’s natural defense, overreacts to something in your environment. For example, pollen, which is normally harmless, can cause your body to overreact.
This overreaction can lead to:
-
A runny nose
-
Sneezing
-
Blocked sinuses
-
Watery eyes
