Find Out What Is Irritating Your Skin

Access Allergy and Immunology provides Patch Testing for Contact Dermatitis in El Paso to identify delayed allergic reactions to chemicals, metals, and fragrances.

When your skin reacts to something you touch repeatedly but you cannot pinpoint the cause, it can affect your daily comfort, your work, and even your confidence. Patch Testing for Contact Dermatitis in El Paso helps identify the specific substances triggering delayed allergic skin reactions that do not show up in standard allergy testing. Access Allergy and Immunology applies small amounts of potential allergens to your skin and evaluates the sites over several days to determine which substances are causing inflammation, redness, or itching in your routine environment in El Paso.

This type of testing is used when you have ongoing rashes, dry patches, or irritation that appears hours or days after contact with certain materials. Common triggers include nickel, fragrances, preservatives, latex, adhesives, and ingredients in personal care products or cleaning supplies. Testing helps uncover the hidden causes behind chronic skin issues that have not responded to typical treatments or that keep returning despite changes in soap, lotion, or laundry detergent.

If you are dealing with unexplained skin irritation that seems linked to what you touch or wear, contact Access Allergy and Immunology in El Paso to schedule patch testing and start identifying your triggers.

Testing uses adhesive panels applied to your back for multi-day evaluation

During your first visit in El Paso, small amounts of suspected allergens are placed on adhesive patches and applied to your upper back. You wear the patches for 48 hours without getting them wet, and then return to the clinic for the first reading. The patches are removed, and your skin is examined for redness, swelling, or blistering at each test site.

You return again after 96 hours for a final reading, as some reactions take longer to appear. Once testing is complete, you receive a detailed list of the substances you reacted to and guidance on how to avoid them in your daily life. Results guide avoidance strategies for personal care products, workplace exposures, and household items.

The test does not measure immediate allergic reactions such as hives or anaphylaxis, and it is not used for food allergies or respiratory symptoms. It is specifically designed to detect delayed contact hypersensitivity. El Paso residents benefit from identifying environmental and occupational irritants specific to the region. Follow-up visits ensure accurate interpretation and long-term skin health planning.

These answers come from real patient questions

Here are some of the most common questions patients in El Paso ask before beginning patch testing, with answers based on how the service is delivered at Access Allergy and Immunology.

What should I avoid before patch testing?
You should avoid using oral steroids or strong topical steroids on your back for at least one week before testing, as these can suppress the skin reaction and lead to inaccurate results. Your provider will give you specific instructions during scheduling.
How long do I need to wear the patches?
The patches stay on your back for 48 hours, during which time you cannot shower, swim, or exercise heavily. After removal, your skin is evaluated again at 96 hours to capture delayed reactions that develop more slowly.
What happens if I have a positive reaction during the test?
A positive reaction appears as redness, swelling, or small blisters at the test site. These reactions are expected and are part of how the test identifies your allergens. Your provider will document each reaction and explain what it means for your daily exposures.
Can patch testing identify all causes of my rash?
Patch testing detects delayed allergic reactions to specific substances, but it does not identify irritants, infections, or other skin conditions. If your rash has multiple causes, your allergist may recommend additional evaluation or referral to a dermatologist.
Will I get a list of products to avoid after testing?
Patch testing detects delayed allergic reactions to specific substances, but it does not identify irritants, infections, or other skin conditions. If your rash has multiple causes, your allergist may recommend additional evaluation or referral to a dermatologist.

If you have chronic skin irritation that seems connected to what you touch, wear, or use daily, Access Allergy and Immunology in El Paso can help you identify the cause through patch testing and give you a clear plan for avoiding further reactions.
