A optimistic outcome means that the sample includes feasible microorganisms, which calls for further more investigation and could cause the rejection in the batch.
PMCID: PMC7315024 PMID: 32321785 Sterility testing of mobile therapy products combined with the involved environmental checking needs for aseptic amenities, like compounding pharmacies, continues to affect clinical microbiology laboratories, as evidenced by the many discussions recurring on American Culture for Microbiology Division C and ClinMicroNet listservs.
