How Can Metal Allergies Be Diagnosed?

Metal allergies can be diagnosed through patch testing, a specialized skin test performed by dermatologists or allergists. During patch testing, small amounts of metal allergens are applied to the skin (usually on the back) and covered with adhesive patches for a specific period. After a few days, the patches are removed, and the skin is examined for any signs of allergic reactions (such as redness, swelling, or rash).
