About the AR Lab Network

Laboratory tests can help guide patient treatment, detect emerging threats, and prevent the spread of antibiotic resistance. CDC’s AR Lab Network supports nationwide lab capacity to rapidly detect antibiotic resistance and inform local responses to prevent spread and protect people.

The network closes the gap between local capabilities and the data needed to combat antibiotic resistance by providing:

• Comprehensive lab capacity and infrastructure for antibiotic-resistant pathogens
• Cutting-edge technology, like DNA sequencing
• Data to drive response and prevent infections

The AR Lab Network includes labs in 50 states, several cities, and Puerto Rico, including seven regional labs and the National Tuberculosis Molecular Surveillance Center (National TB Center).
