skin prick test-Roxall Medicina España S.A

skin prick test-Roxall Medicina España S.A refers to a group of four biological allergen extracts—derived from the pollens of *Dactylis glomerata* (cocksfoot grass), *Lolium perenne* (perennial ryegrass), *Secale cereale* (rye), and *Olea europaea* (olive tree)—undergoing biological standardization by Roxall Medicina España S.A. These extracts are used for the diagnosis of allergic conditions via skin prick testing and for therapeutic allergen immunotherapy. The standardization process involves determining the Histamine Equivalent Potency (HEP) or Skin Prick Test (SPT) value by comparing the wheal size induced by the extracts to a histamine reference in sensitized individuals, ensuring consistency and safety in clinical use for patients with allergic rhinoconjunctivitis and other inhalant allergies.
