Precise to tissue processing and preservation, Nelson Labs gives regime USP and EP compendial exams for microbial enumeration research to assess objectionable organisms and standard bioburden tissue tests for normal bioburden load assessments.
This procedure is relevant to all parenteral pharmaceutical dosage varieties and any specific product for which this exam is mentioned in specification.
The sterility check will only detect or display the existence of All those microorganisms that may improve under the offered check circumstances even though testing products suspected of weighty microbial contamination.
