Compendial microbiological testing is designed to confirm that nonsterile pharmaceutical products meet defined microbiological acceptance criteria prior to release and throughout stability studies. These tests help manufacturers demonstrate control over bioburden, confirm the effectiveness of microbial limits and validate that products remain safe and suitable for patient use.
In aligning testing with recognized pharmacopeial standards, manufacturers can support submissions, inspections and ongoing compliance obligations with reduced risk. Perritt Laboratories works closely with clients to make sure testing programs are appropriate for the product, manufacturing process and intended markets while remaining aligned with current regulatory expectations.
