[0002] The skin scratch test is a commonly used physical examination method in dermatology. It is used to examine allergic skin diseases such as urticaria, drug rash, atopic dermatitis, etc. When the skin is suspected to be allergic to a certain allergen, a specific skin scratch test is needed. Usually, after disinfecting the skin on the outside of the upper arm or the back, use the tip of a needle to scratch a 0.5-1 cm long streak on the skin until there is no bleeding. Then drop the test substance on it and gently wipe it off.
