Typical symptoms of a Skin Allergy often include redness, itching, swelling, and rash. The affected area may become dry, and flaky, or develop small blisters that can ooze or crust over. These symptoms can appear suddenly after exposure to an allergen such as certain plants, chemicals, metals like nickel, or skincare products. In some cases, hives, which are raised, with itchy welts, may develop rapidly and vary in size. The severity of symptoms can range from mild irritation to intense discomfort, and the reaction may be localized to one area or spread over larger skin regions depending on the allergen and exposure.

Other common signs include warmth or tenderness in the affected skin, burning sensations, and sometimes pain if the skin is broken or infected from scratching. Chronic skin allergies can lead to thickened or cracked skin due to repeated scratching and inflammation. It is important to note that symptoms can differ between individuals and may mimic other skin conditions, so professional evaluation is recommended if symptoms persist or worsen. Early identification and avoidance of the allergen often help reduce the severity and duration of the reaction.

The time it takes to receive results from Skin Allergy Testing depends on the type of test conducted. For skin prick tests and intradermal tests, results are typically available within 15 to 20 minutes. During this time, the skin is observed for immediate reactions, such as redness, swelling, or the formation of a wheal (a raised bump). These quick results make skin prick testing an efficient diagnostic tool for identifying immediate hypersensitivities, such as those associated with pollen, pet dander, or insect venom. The healthcare provider will review the results during the same session and provide guidance on next steps.

For Patch Testing, which is used to identify delayed allergic reactions to substances like metals, fragrances, or preservatives, the process takes longer. The patches are applied to the skin and remain in place for 48 hours, after which they are removed, and the skin is evaluated for reactions. A follow-up visit is usually scheduled 72 to 96 hours after the initial application to check for any delayed responses. While the patch testing process takes more time, it is highly effective for diagnosing contact allergies and providing detailed insights into long-term sensitivities.
