Precise Allergy Management: Standardized Cat Hair and Cat Pelt Extracts

Cat allergens are universally present in U.S. homes. They pose a risk of allergic sensitization to everyone, regardless of pet ownership.¹ Accurate options for diagnosis and treatment are essential in addressing this widespread issue effectively.

Inconsistencies in testing and treatment options can hinder the accuracy of allergy diagnosis and impede successful treatment outcomes for patients.

At HollisterStier Allergy, we understand the challenges healthcare professionals face when testing and treating cat allergies. That’s why our manufacturing process targets specific levels of Fel d 1 for greater lot-to-lot consistency in our product.

Cat Extract

Why Choose Our Standardized Cat Hair & Pelt Extracts?

  • Thorough Cat Allergy Evaluation: Gain a comprehensive understanding of patients’ allergies by testing with cat hair and cat pelt. This approach is beneficial, as cat pelt extracts contain higher albumin content and address the needs of the approximately 22% of cat allergy patients.²
  • Reliable Concentration: Using the exclusive Acetone Precipitated (AP) manufacturing process enables us to target specific levels of Fel d 1 for lot-to-lot consistency, maintaining stricter potency adherence than required by the FDA.4
  • No Phenol: Like all of our antigens, our standardized cat extracts do not contain phenol, which can denature proteins in allergenic extracts.3

Choose HollisterStier Allergy’s Standardized Cat Hair and Cat Pelt allergy extracts for precision and consistency in diagnosing and managing cat allergies. With this product in hand you can confidently address the difficulties of cat allergies and deliver optimal care for your patients.
