Abstract

A method to determine a reuse period for a high-level disinfectant without the need to perform a chemical test on the disinfectant during the reuse period. An algorithm for achieving a reuse period during which retesting is not required and based upon desired user stringency is disclosed. A computer program may be used to perform the algorithm. During the reuse period, the disinfectant is maintained in excess of the minimal effective concentration and may be reused on the same device after initial use or on a plurality of used devices. The method provides advantages in terms of cost and time efficiency since it eliminates the need to separately test the composition, and decreases variables associated with repeated testing of the disinfectant.
