This MLT method validation protocol is intended to establish the method for demonstration which the test specimens to which the test for Microbiological Assessment of Nonsterile Products: Microbiological Enumeration and Tests for Specified Organisms are utilized, don't of themselves inhibit the multiplication, underneath the test situations of microorganisms Which may be present.

If there is absolutely no expansion of this sort of type of colonies, or even the identification tests are adverse it indicates absence of Pseudomonas aeruginosa along with the sample passes the test.
