SKIN ALLERGY TESTING AT ADV IN FULLERTON: IDENTIFYING THE TRIGGER

A dermatological patch test does not involve needles or pain. The test is performed by taping tiny, round patches infused with various skin allergens on your back. The patch test is left in place for 48 hours so there is sufficient exposure to the substances for a reaction to occur. After 48 hours, the first reading is taken by our dermatologist at ADV. Another diagnostic reading is taken after a subsequent 24 to 48 hours. The entire procedure is simple to perform, and involves three appointments at our clinic over a week’s time. An accurate identification of the substances triggering an unpleasant, uncomfortable skin reaction can help you avoid those substances in the future and improve your quality of life.

 


COMMON SKIN ALLERGENS

Some of the most common allergic reactions are from poison oak or poison ivy, but allergic skin dermatitis can be triggered by many other substances. Some of the most common substances that cause an allergic reaction include:

  • Nickel
  • Cleaning products
  • Latex
  • Citrus fruits
  • Fragrances in cosmetics, soaps, shampoos, etc.
  • Skin medications
  • Hair straightening products
  • Hair dye
  • Chemicals used to tan leather

 

Only a tiny amount is needed to perform the test, and the substances should be labeled with their chemical names and what they are typically called in your industry. Bring samples of any cosmetics you commonly use, including nail polish, moisturizer, perfumes, sunscreen and others.

 


 

RESULTS 

The results of skin exposure to the various potential allergens in skin patch testing will be professionally evaluated to identify the substances causing a reaction. For some patients who work with various chemical substances, you may be asked to bring in samples of these substances one week prior to testing so they can be prepared for your skin patch test.

 

THE PATCH TEST FOR CONTACT DERMATITIS

Preparing for testing requires you to avoid sun exposure to your back for four weeks prior to testing. You cannot swim, exercise, or engage in any activity that leads to excessive sweating during the time the test is in process. Your back must be kept completely dry so you will need to avoid baths or showers for the duration of the test.

 

SKIN RASHES:WHAT TO DO

If you have developed itchy, rashy skin, it is important to have it checked by one of our highly-skilled dermatologists at ADV in Fullerton. Some rashes can be a symptom of a more serious medical condition. If you commonly experience red, itchy skin, skin rashes, or blisters, connect with us at ADV to perform a patch test to identify the allergen causing the reaction.
