People with skin allergies may experience different symptoms, such as itching, swelling, and rashes, among others. If you have these forms of discomfort, see a specialist for proper diagnosis and treatment. Here are a few ways to test for a skin allergy:
1. Patch Testing
An allergist uses the patch testing method to determine if you have contact dermatitis, which causes redness and blisters on the skin. During this procedure, a specialist applies small amounts of various allergens to your back using adhesive patches. These patches remain on your back for several hours, allowing your skin to absorb the allergens. After this period, an allergist removes the patches and examines your skin for any reactions, such as redness or swelling. The main goal of patch testing is to identify what metals, fragrances, or preservatives trigger your allergies.
2. Skin Prick Testing
A trained healthcare professional performs skin prick testing to determine if your skin is allergic to pollen, pet dander, and certain foods. To begin the process, this specialist reviews your medical history and discusses medications you are taking, like antihistamines, which interfere with test results. The test is performed on your forearm or back, where the outer layer of your skin absorbs a specific allergen. After some minutes, an expert checks the area for reactions such as a raised bump or redness. By knowing what stimulates your allergies, a provider may prescribe medications and advise you to avoid exposure.
3. Blood Tests
Blood tests are used to determine a skin allergy when a patient has conditions like eczema that interfere with accurate testing.During this procedure, a healthcare provider draws blood from your arm and sends it to a lab for testing. Tests may include measuring total immunoglobulin levels for allergens, including pollen, pet dander, or certain foods. By measuring immunoglobulin levels, an allergist may know how severe your allergic responses are and the risks associated with being exposed to some contaminants. Once a professional has your results, they are able to prescribe topical corticosteroids and immunotherapy to help manage these allergies.
4. Elimination Diets
Elimination diets are useful for identifying food allergies when symptoms affect the skin, like eczema or hives. This process includes removing suspected foods from your diet that might be causing skin allergies. You avoid eating common allergens such as dairy, gluten, or nuts to help a specialist know what you are allergic to. Throughout this phase, a provider closely monitors your symptoms and records changes in your condition. Improvement in symptoms during this time may indicate that one or more eliminated foods were contributing to your allergic reactions. After this period, an allergist introduces new foods and observes the reactions each of them is causing for proper treatment.
