Microbiologics have published a new post highlighting the best practices that auditors look for when evaluating growth promotion testing (GPT). By referencing the various Pharmacopoeia (Ph. Eur., USP, JP) they discuss some of the key questions pertaining to GPT:
- When must you perform?
- What are the requirements for the challenge organisms used?
- Do you need to test each “batch” when a new LOT number arrives, or do you need to test each delivery regardless of LOT number?
- What are the differences when growth promotion testing solid versus liquid media? And dehydrated media versus ready-to-use (RTU) media?
