ulmus parvifolia pollen

Ulmus parvifolia pollen is a non-standardized biologic allergen extract derived from the pollen of the Chinese elm tree (*Ulmus parvifolia*). It is primarily utilized as a diagnostic tool in allergy testing to identify individuals with hypersensitivity to Chinese elm pollen. The extract is administered via percutaneous (skin prick) or subcutaneous injection, where it triggers a localized IgE-mediated allergic response in sensitized patients, resulting in a wheal-and-flare reaction. It is manufactured by Jubilant Hollisterstier and is FDA-approved for use in allergenic testing.
