Elm, a member of the Ulmaceae family, is a wind-pollinated deciduous tree that produces pollen allergens eliciting type IgE hypersensitivity on exposure through nasal inhalation manifesting with nasal symptoms of rhinitis, ocular allergy, pneumonitis, anaphylaxis, atopic dermatitis, and exacerbation of bronchial asthma. Healthcare providers utilize this diagnostic tool to ascertain patients’ allergenicity and provide guidance for allergen-specific immunotherapy.
Important note: Minimum volume is 1 mL and 0.5 mL for every additional allergen.
