The Food and Drug Administration (FDA) has issued an updated version of its Compliance Policy Guide for Pre-Approval Inspections (PAI). This article will guide you on this policy’s impact on analytical procedures and data included within regulatory submissions.

Do You Understand the FDA’s Updated Approach to Pre-Approval Inspections?

Data integrity has been the subject of many “Focus on Quality” columns over the past few years (1–5). However, we have never mentioned, let alone discussed, data quality. 

Data Quality and Data Integrity Are the Same, Right? Wrong!

Analysis of FDA Form 483 observations and warning letters for infrared spectrometers reveals a range of data integrity problems and a lack of laboratory procedures for the technique. Is your laboratory in the same situation?
