Allergy can be considered an abnormal response of the immune system. The defense mechanisms present in the blood of our body identify foreign substances and work to eliminate their harmful effects. Individuals with an allergic predisposition have an immune system that develops an exaggerated reaction to substances like pollen, mold, pet dander, and other typically harmless materials. Factors such as genetics, air pollution, cigarette smoke, and infections also contribute to the development of allergies.

Allergic reactions on the skin usually manifest as redness, swelling, and itching.

Allergy Tests for Skin Diseases

Allergy tests are diagnostic tools used to identify the allergens that trigger symptoms in allergic skin conditions. Since the mechanisms causing allergic reactions differ, the appropriate tests are determined by your dermatologist based on the specific disease. The most commonly used allergy tests in dermatology include:

• Patch Test
• Photopatch Test, Atopy Patch Test
• Prick Test
• Intradermal Test
• Autologous Serum Test
