USP <797> sets practice standards to ensure that compounded sterile preparations are of a high quality and free of contamination. Many of these guidelines are directed at air quality monitoring and analysis.
Criterion can assist you in your compliance efforts with reliable environmental monitoring and analysis, a vital component in meeting USP <797> requirements in your commercial or hospital pharmacy, clinic or physician's office. We can perform the monitoring for Class 5 and Class 7 areas, including the screening and analysis of viable bacteria and fungi in the air, gloved fingertips, surface contact plates and non-viable particulates.
We can also provide guidance in rating Level 5 clean rooms as low, medium, or high risk, though the final decision must be made by the Lab Manager.
Aseptic techniques are followed on all sampling and analysis methods. Criterion personnel use pharmacy garb.
A report will be issued detailing sample locations, results, recomendations, if any, collection methods and time after compounding activities, if any.
