Skin Allergy Testing (Skin Test)

A skin allergy test involves lightly scratching the skin with a fine needle point to allow the testing solution to absorb into the skin. After waiting 15 minutes, if the patient is allergic to a specific allergen, a reaction such as a raised, swollen, and red welt will appear at that site.

In general, testing can be performed on individuals of all ages and genders. However, in infants younger than 6 months and in elderly individuals, false-negative results may occur due to decreased skin sensitivity.

Before the test, antihistamines, cold medications, and decongestants must be discontinued for at least 7 days.
