Is it possible to have a severe allergic reaction during an Advanced Patch Testing session?

If you are bothered by persistent rashes that cannot be explained, advanced patch testing is a scientific way to pinpoint the allergen responsible. However, in order to identify the offending irritant, a range of possibleallergens are used. This methodology often causes patients to ask their doctor – “Is it possible to have a severe allergic reaction during an advanced patch testing session?”

What is an advanced patch test?
An advanced patch test is a method used to help determine which specific substance is causing a patient’s allergic contact dermatitis (ACD). It helps the doctor distinguish between the 2 common types of contact dermatitis, – irritant and allergic.  ACD occurs when a specific allergen comes in contact with the skin. A patch test is used to find the cause of this reaction.

How is it done?
The doctor will place strips of non-allergic tape on your backon which small amounts of substances that commonly cause ACD are applied. The patches are usually removed after 2 days, and the doctor will then interpret the results. Another examination takes place 2 days later, as a delayed reaction can occur.

Can severe allergic reactions occur?
Since a range of allergens are included in the testing, a patient’s reaction may vary from mild to strong irritation. Therefore extreme reactions such as blisters and ulcers can occur. It depends on the specific allergen.
