**Two A2LA accreditations cover this service:** Allometrics Cert 2039.01 (ISO/IEC 17025 calibration) governs the sample-handling and field-deployment QC. Taylor Lake Laboratories Cert 7533.01 (ISO/IEC 17025 biological testing) governs the laboratory analysis itself. Same group; same accreditation chain.

Why monthly USP <797> environmental monitoring matters

USP <797> requires sterile compounding pharmacies to perform routine environmental monitoring of their PEC (Primary Engineering Controls) and SEC (Secondary Engineering Controls). The frequency: viable air sampling at least every 6 months in low-risk facilities, monthly in high-risk and Category 2 / Category 3 facilities.

If your monthly EM data shows out-of-spec viable counts and you cannot demonstrate corrective action, your batches go on hold. State boards of pharmacy and FDA inspectors review EM trend data as part of every inspection. The cost of a robust monthly EM program is small compared to the cost of a batch hold or a deficiency notice.

Allometrics' integrated cleanroom certification + viable air sampling team performs both certifications and EM in the same visit — under one accreditation chain, with one report deliverable.
