Investigations of Microbiological Laboratory Data

Webinar to be presented Thursday, August 16 at 2pm EST


What did the Microbiology lab do wrong? This is generally the first question asked when unpleasant data is reported about finished product.

The FDA Guidance document on OOS specifically excludes microbiology from its scope, but this does not release the manufacturer from his obligation to investigation product failures for microbiology-based quality specifications. Before getting to this stage, however, we have to have complete confidence in the microbiology lab data.

This webinar will present a proven method for performing laboratory investigations to establish the validity of microbiology test results, whether from an internal resource or a contract testing lab. This method relies heavily on a well-designed SOP system and proactive documentation. Additional benefits to this method include enhanced GMP compliance. The approach presented will also be invaluable in audit and investigation of contract laboratory reports, an area of increased regulatory scrutiny.

Be sure of your data before reporting product issues!
