Dose Mapping Requirements – Understanding the Historic and Current Practices

Available on Demand until July 19, 2018

Historically, the Medical Device/Pharmaceutical/Biologics industry has experienced inconsistencies with respect to Gamma PQ Dose Mapping requirements for product deemed as sterile according to ANSI/AAMI/ISO standards.

Healthcare products have dramatically evolved over time, and are less likely to be homogeneous in composition.  Along with new combination products, material composition and packaging have made it necessary to place dosimeters within the product box in order to measure the minimum dose.  As a result, there is a requirement for triplicate dose mapping in order to measure the dose distribution and assess the process variability.

This Webinar will help clarify historical practices and current practices and guidance with respect to Gamma PQ Dose Mapping.
