This document summarizes sterility testing procedures for pharmaceutical products. Sterility testing aims to detect any viable microorganisms That could be existing. Samples are inoculated into fluid thioglycollate medium, option thioglycollate medium, or soybean-casein digest medium and incubated with test microbes like S.
Bioburden or microbial limit testing on these products proves that these necessities are actually achieved. Bioburden testing for health-related equipment created or used in the United states is ruled by Title 21 on the Code of Federal Rules and throughout the world by ISO 11737.
