In the pharmaceutical industry, this is known as OOS (Out of Specification) โ a critical quality event that requires immediate investigation.
An OOS result indicates that a raw material, in-process sample, or finished product does not meet predefined quality standards. These investigations play a vital role in maintaining GMP compliance, ensuring product quality, and protecting patient safety.
