Allergy Testing

by Sherwin Hariri, MD, FAAAAI, FACAAI

What is patch skin testing?

Patch skin testing is performed to determine what allergen is causing a delayed allergic skin reaction. It is often very useful in identifying the cause of different types of skin rashes patients present with. Potential allergens are different chemicals, metals, dyes, preservatives, rubbers, and many other substances. During the patch test, your skin will be exposed to allergens and your reaction will be noted over a period of time to determine if you have a sensitivity to that substance. In some cases, it can take several days for a skin reaction to occur.  Therefore, the patch test results will not be read until 48 to 96 hours after applying the patches to the patient's skin. The results of your patch test can help Dr. Hariri determine the best course of treatment to help you avoid allergic reactions and significant skin rashes.

How is patch testing performed?

In a patch test, allergens are applied to special skin patches, which are placed on your the skin of your back or arm and allowed to remain there for about 48 hours. A single patch tests can include as many as 20 to 30 different substances for testing, including dyes, preservatives, resins, fragrances and other substances. While the patches are in place, you'll need to avoid bathing or participating in exercises that could cause you to perspire, which can wind up diluting the substance and causing a false result. When you return to the doctor to have the patches removed, Dr. Hariri will look for signs of skin reactions or irritation and determine if they indicate an allergy.

Can patch skin tests be performed on anyone?

Skin patch tests may not be a good choice for people who have a history of severe allergic reactions, who take medicines that could interfere with results or have certain skin conditions.
