When the skin comes into contact with a substance to which it is allergic or hypersensitive,
its reactions can include swelling, redness or blisters, itching, or a burning
What Are The Symptoms of a Skin Allergy?
Different allergies have different symptoms, but the most common symptom is
an itchy rash, often with blisters. There can be stinging or burning as well,
and the rash can also ooze, crust, or peel.
How Is A Skin Allergy Diagnosed?
A skin rash can be caused by either an irritant or an allergy, and its location
on the body sometimes helps in diagnosing its cause. A skin prick test or patch
test can be used to help identify the particular allergen.
How Is Skin Allergy Patch Testing Done?
A skin patch test is used to check for allergic reactions to many substances at
the same time.
||For this test, paper tapes containing small amounts of many common allergens
are applied to the back and left in place for two days. At that time, the
doctor will remove the tape and study the results, looking for the redness
or blisters that indicate an allergic reaction. The skin patch tests are
quick, simple procedures that are safe and produce little discomfort.
