USP seventy one sterility testing assists be certain products labeled as “sterile” are absolutely free from damaging microorganisms.
Microbial identifications will also be performed to characterize the bioburden load and kind. Special concerns arise with tissue products, specially inhibition because of the usage of antibiotics for preservation of tissue materials, which should be validated using a suitability review prior to carrying out some program checks.
