albumin (human) + phenol + glycerin

**albumin (human) + phenol + glycerin** is a sterile biologic diluent solution used in allergen immunotherapy and allergy skin testing preparation, rather than a direct pharmacologically active therapeutic ingredient. It is used to prepare serial dilutions of allergenic extracts and to help preserve extract stability and potency during storage and administration. In this formulation, human serum albumin functions primarily as a protein stabilizer that reduces loss of allergen activity through adsorption and degradation, phenol serves as an antimicrobial preservative, and glycerin contributes additional stabilization and preservation of allergenic extracts. The product is associated with Jubilant HollisterStier and is used in the management workflow for patients with immediate hypersensitivity to specific allergens, including preparation of materials for diagnostic skin testing and allergen immunotherapy.
