According to USP 797, how often should a compounder performing high-risk preparation undergo validation testing?

• A. Every 6 months
• B. Once a year
• C. Every 3 months
• D. Weekly

Answer: (A)

High-risk compounding requires validation testing on a semiannual basis. This interval exists because high-risk preparations pose a greater chance of contamination, so ongoing verification of both the operator’s aseptic technique and the cleanroom environment is essential. Validation testing typically includes a media-fill test to simulate actual aseptic manipulations and gloved fingertip sampling to confirm that technique remains sterile, along with environmental monitoring of air and surfaces. Performing these checks every six months provides a regular, proactive checkpoint to catch any drift in technique or environment before contamination could affect patient safety. If problems are detected, testing can be done more often, but semiannual validation is the standard expectation for high-risk work.
