Skin Allergy

Allergic contact dermatitis is a common skin condition in which patients have become sensitized to a particular allergen or chemical in their environment and suffer from a persistent itchy rash, usually localized to the area in which the patient is exposed to the allergen. It can be extremely difficult to isolate the problem, since in many cases, patients may have been using the problem product for years without issues.


Through history and physical examination of the patient, Dr. Khilji Faisal Arif can find clues to what are the allergens, which may be causing the rash. However, in many cases, your provider may need to perform tests, such as patch tests to really identify the problem clearly. Patch tests are a safe and easy way to diagnose contact allergies.

Patch tests are different from injection or scratch skin tests because they test for different allergens. In patch tests, small amounts of the possible common allergens are applied to the skin on panels and secured with tape if necessary. A positive allergy test shows up as a small red spot at the site of the patch.


Patch tests have little or no pain. However, positive reactions may cause itching and red bumps which look and feel like insect bites. The bumps and itching resolve generally quickly.
