Aureobasidium pullulans is a yeast-like fungus found in soil and plant surfaces, which may lead to type 1 hypersensitivity to its allergens in some individuals. Upon exposure, IgE antibodies trigger the release of histamine and other mediators, causing allergic symptoms ranging from rhinitis, rhinoconjunctivitis, dermatitis, atopy, or severe anaphylaxis. Healthcare professionals use this test to determine allergic status and guide allergen-specific immunotherapy.

Important note: Minimum volume is 1 mL and 0.5 mL for every additional allergen.
