This MLT technique validation protocol is created to establish the strategy for demonstration that the test specimens to which the test for Microbiological Examination of Nonsterile Products: Microbiological Enumeration and Tests for Specified Organisms are utilized, usually do not of on their own inhibit the multiplication, under the test disorders of microorganisms That could be current.
Prior to undertaking MLT testing on a product, the method needs to be validated to ensure that the product has no microbial inhibitory Homes which could end in Bogus negatives.
