Warning Letter: No active audit trail (ucm443247)

“Failure to prevent unauthorized access or changes to data and to provide adequate controls to prevent omission of data.

You lacked controls to prevent the unauthorized manipulation of your laboratory’s electronic raw data. Specifically, your infrared (IR) spectrometer did not have access controls to prevent deletion or alteration of raw data. Furthermore, the computer software for this equipment lacked active audit trail functions to record changes to data, including information on original results, the identity of the person making the change, and the date of the change. Audit trails that capture such critical data about the quality of your batch production should be reviewed as part of the batch review and release process.”
