Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (MBC) Tests

Purpose of Test As an adaptation of the clinical susceptibility tests commonly used to determine effective concentrations of antibiotics, the MIC and MBC test method can be performed as a presumptive way to screen active concentrations of a product. This method is not typically used to generate antimicrobial claims with a specific regulatory agency but… Read More

Re-Use Stress Testing and Evaluation of Disinfectants

Purpose of Test The U.S. FDA and Health Canada require that high-level disinfectants intended to be continuously reused in a clinical setting be evaluated for efficacy after the product has been subjected to simulated re-use procedures. The purpose of this method is to generate a product which has undergone simulated use and periodic bio-burden stressing.… Read More
