CDC’s Antibiotic Resistance (AR) Laboratory Networks

ARLN Training Lab

Lab tests can help detect emerging threats and prevent the spread of antibiotic resistance.

CDC’s antibiotic resistance laboratory networks support lab testing in health care, the community, and the environment (e.g., water, soil). This work ultimately improves patient care, enhances public health, and informs solutions against resistance threats. 

CDC’s Antibiotic Resistance Laboratory Network (AR Lab Network), established in 2016, provides nationwide lab capacity to rapidly detect antibiotic resistance and inform local responses to prevent spread and protect people. It closes the gap between local capabilities and the data needed to combat antibiotic resistance in the U.S.

CDC’s Global Antimicrobial Resistance Laboratory & Response Network (Global AR Lab & Response Network), launched in 2021, improves the detection of existing and emerging antibiotic resistance threats outside of the U.S. It identifies risk factors that drive the emergence and spread of resistance across health care, the community, and the environment. This global network also supports local public health responses to stop these threats and informs global prevention strategies for antibiotic resistance.
