Accredited microbial testing for USP <797> compliance — from cleanroom environmental monitoring to media fill kit analysis.
All Taylor Lake Laboratories services are performed under our A2LA accreditation (Cert. No. 7533.01) to ISO/IEC 17025:2017. Our accredited scope covers microbial enumeration, microbial identification, and media fill kit analysis on samples from cleanroom environments — tested to USP <797> and our validated standard operating procedures.
Routine environmental monitoring (EM) is a core requirement of USP <797> for sterile compounding facilities. Taylor Lake Laboratories provides accredited analysis of air and surface samples collected from your ISO-classified cleanroom environments.

USP <797> requires regular assessment of personnel aseptic technique through gloved-fingertip and thumb sampling. Our accredited testing helps verify that your compounding staff meets contamination control requirements.

Media fill testing is a critical tool for demonstrating that your aseptic technique and compounding process does not introduce contamination. Taylor Lake Laboratories provides accredited incubation and analysis of media fill units prepared at your facility.
