leymus condensatus pollen

Leymus condensatus pollen is an allergen extract derived from the pollen of *Leymus condensatus*, commonly known as giant wildrye, a perennial grass native to the western United States and northern Mexico. This biological product is used primarily as a diagnostic tool in allergy testing, such as skin prick tests or in vitro IgE assays, to identify individuals with hypersensitivity to this specific grass species. The extract contains allergenic proteins that, upon exposure in sensitized individuals, cross-link specific IgE antibodies on the surface of mast cells and basophils, triggering the release of inflammatory mediators like histamine. This reaction allows clinicians to diagnose allergic rhinitis, conjunctivitis, or asthma associated with giant wildrye pollen exposure.
