Validation of Rapid Methods and Systems

Microbiological testing is significant in the pharmaceutical laboratory for many reasons. The testing is used determine the microbiological quality and attributes of the environment, materials, utilities, and products. Unfortunately, it is also recognized for being a critical factor in determining product release times. This chapter provides guidance on the validation of the equipment, software and methods.


Validation of Sterility Test Suites and Isolators

Performance of the classical compendial sterility test provides very little information regarding whether the product is sterile. Numerous articles point out the deficiencies of the test, including the small sample size, test methods used, recovery and incubation conditions, etc. The test is incapable of showing whether a product provides a sterility assurance level (SAL). This chapter discussed the methods used to validate the sterility testing area.
