FDA Makes Up-to-Date Susceptibility Test Interpretive Criteria (Breakpoint) Resources Available Online

December 14, 2017

The US Food & Drug Administration (FDA) has taken an important step to improve public health by creating a website to make critical updates regarding antimicrobial drugs available to health care professionals. This information helps laboratories report the most current information to health care providers about what type of infection a patient has and what the most effective treatment will be. The website provides information on the most up-to-date Susceptibility Test Interpretive Criteria (STIC), also known as breakpoints. Breakpoints help determine whether a specific bacteria or fungi are susceptible to (ie, will respond to treatment with) antibacterial or antifungal drugs. According to the FDA, “This approach is intended to aid health care professionals in making more informed prescribing decisions that will both benefit their patients and prevent the spread of resistant bacteria.”
