The Most Common Types of Allergy Tests Performed Include:
Skin Prick Tests: Skin prick allergy testing is the most common and is virtually painless. A very small amount of certain allergens are applied to your skin by making a small indentation or “prick” on the surface of your arms (or back) using plastic pricks. This type of testing is utilized to test for environmental, food and/or spice allergies. If you have allergies, a small red bump similar to a mosquito bite will appear on the skin. Positive reactions generally occur within about 20-30 minutes thus allowing you to see what you are allergic to during your visit. And generally the small hives where the tests were done will go away within 30 minutes. After the testing, ice and creams may be applied locally to reduce any redness and itching at the test sites.
Intradermal Tests: If your prick skin tests are negative but your allergist still suspects you might have allergies, more sensitive tests may be used in which a small amount of allergen is injected within the skin. This type of testing may also be utilized to confirm your allergies and determine your sensitivity for purposes of making your serum for allergy immunotherapy (allergy shots or drops).
Challenge Tests: A very small amount of an allergen is inhaled or taken by mouth. Challenges are done mostly with potential food allergies. Challenge tests are always performed in our office under the supervision of our practitioners.
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. The blood tests are prescribed & Drawn in our office.
Skin Patch Tests: Patch tests are used for skin allergies, also known as contact dermatitis. They can determine if a patient’s skin contact with certain chemicals, metals, fragrances or other things cause a rash or dermatitis. These allergens are applied to a patch that is numbered and placed on your back. Patch tests take more time than skin tests and do not yield an immediate response as with skin testing. You will return to the office after 48 to 72 hours to have the patches removed and your test read.

Allergy testing involves having a skin or blood test to determine what substance may be triggering an allergic response in a person. At Echo Allergy Care we feel that allergy skin testing is the gold standard of allergy testing, but sometimes both skin tests and blood tests may be used. Skin tests are usually performed because they are reliable, rapid, and typically more accurate and less expensive than blood tests. Based on the test results, you will be given a plan of care that will include medication, education and options available to you.
