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.

A patch test is done to determine the underlying cause of the allergic reaction. Based on the results, doctors are able to suggest the most effective treatment.

Patch testing is a procedure that is done to determine the cause of contact dermatitis in patients. The patch test will confirm whether there is an allergic or irritant reaction to a specific allergen.

How is it done?

The substances being tested are applied to the back in special small patches, which are held in place with non-allergenic tape. Substances chosen are those that are frequently in contact with the skin, and may be likely suspects of your skin problem. The patches remain in place until the next visit to the doctor, which is usually within 48 hours. When the patches are removed the physician will examine the skin, and pinpoint any adverse reactions.

Side-effects to patch testing

If there is a positive reaction to the test substance, the skin becomes red and itchy. Thesesymptoms usually disappear within a few days, but in some cases there is a persistent reaction that lasts up to 1 month.  In rare cases patients have developed a burn-like reaction.
