The name of the medicine used in a skin test depends on the type of test. There isn't one single "skin test medicine."
Skin Test Medicines for Different Purposes
-
Tuberculosis (TB) Testing: The medicine used in a skin test for tuberculosis is tuberculin purified protein derivative (PPD). This test helps diagnose TB infection.

Allergy Testing: Allergy skin tests use various allergens, which are substances that cause allergic reactions. These allergens are applied to the skin to determine if a reaction occurs. The specific allergens used will vary depending on the suspected allergy.

Understanding Allergen Testing
Allergy skin testing identifies allergens, the substances causing allergic reactions. The test involves applying diluted amounts of suspected allergens to the skin to observe any reaction. This helps determine appropriate treatment, such as allergen avoidance, medication, or immunotherapy (allergy shots). [Source: Mayo Clinic]
