How to Prepare for an Allergic Skin Test


Allergies happen when the immune system overreacts, which is also called hypersensitivity. Most of the time, the immune system protects the body from viruses and bacteria. For people who have allergies, The immune system thinks that something like dust or pollen is dangerous, even though it is not. The immune system responds to what it thinks is a threat by making an allergic reaction. Some signs of an allergic reaction are sneezing, a runny nose, and a blocked nose.

The substance which causes allergy is called an allergen. A skin test is used to determine what allergens someone is allergic to. The test can tell you which substances (allergens) are causing your allergic reaction. Some of these things are pollen, dust, mould, and even medicines like penicillin.

There are three typical ways to test:

1) Skin prick test placing a small about of allergen on the skin. The skin is then poked so the allergen can get under the skin. Several allergens tested at the same time. Results by 15-20 minutes.

2) Intradermal skin test-injecting a small amount of allergen into the skin and watch for a reaction at the site.

3) Patch testing involves sticking possible allergens to the skin with tape for 48 hours. The area is looked for reaction by 72-96 hours.

Skin tests may cause minor discomfort, itching, a stuffy nose, watery eyes or skin rash if the patient is allergic to the substance. Rarely can an allergy affect the whole body.
