A “program Management” is utilized to reveal maintenance of sample integrity through all analytical manipulations. Any piece of kit that comes in contact with the product less than Examination, coupled with any manipulations by the analysts, need to be managed. Consequently, all tools, fluids, and lifestyle media for that “procedure Management” has to be managed in a fashion which duplicates, as closely as feasible, the manipulations of the particular sample becoming analyzed.
