Injectable Allergen Extracts- Non-Standardized

Injectable Allergen Extracts

Allergen extracts are currently manufactured in two forms: standardized and non-standardized. For the standardized allergen extracts, manufacturers compare the allergen extract to a U.S. reference standard for potency. CBER maintains these reference standards and distributes them to manufacturers. There are currently 19 standardized allergenic extracts.

Extracts for which there are no U.S. reference standards are called non-standardized extracts.
