USP 797 Viable and Non-Viable Environmental Sampling

USP 797 refers to chapter 797 "Pharmaceutical Compounding – Sterile Preparations," in the USP National Formulary. It is the first set of enforceable sterile compounding standards issued by the United States Pharmacopeia (USP). The official publication from 2008 is still the current valid guideline from USP. However an updated publication is in the pipeline and in draft format.
