Allergy Patch Testing

What are contact allergies?

Also known as allergic contact dermatitis, contact allergies refers to a skin condition — typically a red, itchy rash — that occurs when a chemical comes into direct contact with skin, causing an allergic reaction. 

Common allergens that cause contact dermatitis include:

• Metals, such as nickel which is often used in jewelry 
• Rubber or latex 
• Fragrances  
• Topical medications
• Cosmetics
• Plants, such as poison ivy 

The skin rash caused by contact allergies isn’t contagious, but can be very uncomfortable. 

What are the symptoms of contact allergies?

Symptoms associated with contact allergies typically develop on areas of the body that have been directly exposed to chemicals. Allergic contact dermatitis symptoms may include:

• Red, itchy skin
• Bumps or blisters
• Swelling
• Hot or tender skin

Allergic reactions from contact allergies usually occur between two and four days after exposure, but it can also take up to a week to start experiencing symptoms. If you’re experiencing any of the symptoms above, visit Central Park South Dermatology for allergy patch testing. 

What is allergy patch testing?

Allergy patch testing is a noninvasive means of determining which substances cause your allergic reactions. Unlike other forms of allergy testing, patch tests don’t require injections or blood work. If you have recurrent rashes and don’t know the cause, allergy patch testing is a good solution.

The process is simple and straightforward. During your session, your provider at Central Park South Dermatology places a series of small patches or stickers on the surface of your back. Each patch has a small amount of a potential allergen. 

After a period of time, the patches are removed. If the underlying skin is red or shows any sign of inflammation, Dr. Blum and her associates know you’re allergic to that specific substance. They can then work with you to customize an allergy treatment program to suit your specific set of needs. 

How can I prevent allergic reactions?

Knowing which allergens trigger a reaction is important. One of the most effective ways to reduce allergic reactions is identifying and avoiding allergens. By taking steps to alter your living space and limit exposure to allergens, you can greatly reduce the number and severity of allergic reactions you experience. 

There are also treatments that can reduce allergic reactions. Immunotherapy is one approach. It involves introducing minute volumes of allergens to help your body build up a tolerance.
