If you experience irritation after a substance touches your skin, you may have an allergy. However, the only way to be sure that you’re dealing with contact dermatitis is through patch testing. And while the process takes longer than some other allergy tests, it can test for 20 or more allergens at one time. So, what types of allergy can your Atlanta allergist diagnose with skin patch testing?
10 Common Allergies Diagnosed With Skin Patch Testing
Skin patch testing is suitable for a wide range of allergens that frequently cause skin irritation. Here’s a look at some of the most common allergies diagnosed using this type of allergy testing procedure.
1. Antibiotics
An allergy to antibiotics can show itself when being treated for various conditions. For example, penicillin is widely used, but it’s a common cause of allergic reactions.
2. Latex
An allergy to the natural rubber in latex gloves can be an issue for medical professionals and others who require hand protection.
3. Fragrances
After being applied to the skin, fragrances and perfumes can lead to contact dermatitis and headaches. Hypoallergenic products are an alternative choice for allergy sufferers.
4. Sunscreen
Chemicals in many sunscreens can cause skin rashes, itching and hives. Due to the importance of using sunscreen, individuals should use a non-allergic option.
5. Nail Cosmetics
Some types of nail cosmetics such as acrylics, polish and gels can cause fingers to become inflamed and even swell after contact.
6. Topical Corticosteroid
Anti-inflammatory medication can actually lead to skin rashes and itching for many allergy sufferers.
7. Detergent
Laundry detergent may cause an allergic reaction, and this allergy can be diagnosed by the patch test. In contrast, allergy to pet dander or dust is determined with the skin prick test.
8. Metal
Nickel, cobalt, chromium and zinc are often found in everyday items, and many people experience skin inflammation after contact with these metals.
9. Textile Dye
Dyes used for workout clothing, leggings and other items may gradually cause irritation due to close contact with the skin. Skin patch testing will diagnose the allergy effectively.
10. Hair Dye
An itchy scalp and redness are common signs of an allergy to substances in hair dye. This allergy can impact both a client and their hairstylist.
How Does the Skin Patch Testing Process Work?
The process begins with a visit to your allergy doctor, where your back is sterilized to prepare for the test. Patch test chambers (containing potentially more than 100 allergens) are then applied to the back. These must remain in place for 48 hours.
Once the 48-hour wait is completed you will return to your allergist’s office. At this point the patches will be removed, and an initial assessment is made. To complete the skin allergy test you must return after a further 48 hours. Here, signs of dermatitis are analyzed and graded, allowing your allergist to make a proper diagnosis.
How Are the Allergens Chosen for Skin Patch Testing?
Allergists will frequently use a standard number of allergens for the patch test based on the probability of a positive result. This approach to allergy testing will usually allow diagnosis of most of the main allergens experienced by Atlanta-area residents. In addition, a discussion of your allergy symptoms, occupation and medical history may play a role in the process.
