What does the MEC test determine in relation to high-level disinfectants?

The MEC (Minimum Effective Concentration) test is designed to evaluate the potential dilution of high-level disinfectants, which is crucial for ensuring the efficacy of these disinfectants in achieving the necessary microbial kill in the context of flexible endoscope reprocessing. By determining the MEC, one can identify the weakest concentration of disinfectant that is still effective against specific microorganisms. This is important for maintaining safety and functionality, as using a diluted solution that falls below the MEC could lead to inadequate disinfection and increased risk of infection.

In essence, understanding the proper dilution level ensures that when disinfectants are used, they are at a concentration that is effective in destroying pathogens without compromising safety or risking resistance from microorganisms.
