The allergy skin test can be done periodically to determine what allergies a person has. This can also determine the extent of the allergy. Understanding what we are allergic to can help in proper treatment of allergies and also assist in helping us avoid severe allergies.
How a Skin Allergy Test is Done
When you get a skin allergy test, the doctor typically maps out an area of the arm or the upper back that will allow for the test site to be covered by clothing. This allows for a more accurate reading. The test is controlled by marking out which allergen is to be placed where so the readings are completely clear and cannot be mistaken. Typically, the allergy test is done by scratching a needle that contains the “allergen” across the skin. This leaves a small amount of the allergen under the skin.
The results are then read approximately 15 minutes later. The results tell the physician what you are allergic to so you can receive proper treatment.

Treatment For Allergies
Treatment for allergies can be as simple as taking a daily allergy pill, or it can involve allergy shots. Typically, allergy shots are recommended only if you have a severe allergy to a material, or if the reaction to a substance affects your life more than three months out of the year.
Alternatives to Standard Allergy Tests
Intradermal Test: This test is done by checking and cleaning the skin, then injecting a small amount of the allergen under the skin.
Patch Test: The patch test is done by having the patient wear a patch that contains the allergen. Similar to a smokers patch, this works best with allergens that cause an allergic reaction to the skin.
