Standardized Allergenic Extracts
Allergenic extracts are currently manufactured in two forms: standardized and unstandardized. Prior to release standardized allergenic extracts are compared to US reference standards 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 US reference standards are called unstandardized extracts.
