    Medical Service NameContact Allergies (Patch Testing)

    Dermatitis is a common medical term for skin irritation. Contact allergies are a kind of inflammation that causes itchy or painful skin rashes. It mainly happens when your skin comes in contact with any allergy-spreading substances (allergens) such as poison ivy or chemicals. If you have sensitive skin, there’s a high probability of getting affected by contact allergies.

    You might experience this skin issue after a repeated or single exposure to any harmful chemical that causes allergy. Specifically, people working in sectors such as construction, food handlers, hair stylers, Painters, Florists, and healthcare providers are prone to this ailment.

    Contact allergies are mainly of two types – Allergic Contact Dermatitis and Irritant Contact Dermatitis. For the first case, allergy spreads through allergic substances such as metal jewelry, perfumes, and preservatives. In the second situation, these painful rashes tend to come in response to irritants like soap, detergent, and acid cleaners.
