This examine presents probably the most in depth evaluation so far on the USP, BacT/Inform, and Bactec methods for your detection of 118 typical cGMP environmental and biopharmaceutical contaminants and highlights vital restrictions of automated blood lifestyle methods that must be regarded if these platforms are utilized for products sterility testing. Our results differ noticeably from These of earlier research, which have shown equal or far better performance of your automatic blood lifestyle programs, compared With all the compendial USP method (7,–twelve, 15, 28).
