Antimicrobial Resistance Laboratory Network (AR Lab Network)
CDC’s AR Lab Network
- Comprehensive lab capacity and infrastructure for antimicrobial-resistant pathogens, including bacteria and fungi
- 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).
With support from CDC’s Healthcare-associated Infections and Antimicrobial Resistance (HAI/AR) Program and other AR Lab Network members, participating health departments contribute to a national network that can more rapidly detect resistance, respond to outbreaks, and help control antimicrobial resistance.
Through the AR Lab Network, health department HAI/AR Programs monitor for, report, and coordinate follow-up measures when unusual AR is detected in a healthcare facility. Health departments and public health labs also provide healthcare facilities with timely lab results, recommendations, and status updates on discharges and transfers of patients with known resistance to help maintain infection prevention and control.
As part of CDC’s HAI/AR Program, health department HAI/AR Programs implement a wide range of AR Lab Network-related activities, such as:
- Support comprehensive AR testing as part of the AR Lab Network
- Submit isolates of interest to regional labs or CDC for additional or advanced testing as required
- Train and provide guidance to laboratory personnel testing for AR
- Engage and coordinate with clinical labs and healthcare facilities to participate in AR Lab Network testing
- Coordinate with state and local HAI/AR programs, regional labs, and CDC to support action to address AR
Through supplemental funding provided by the American Rescue Plan Act, CDC awarded health departments with additional funding to expand laboratory capacity and public health infrastructure to detect AR pathogens faster and help stop spread, which are critical to preventing the spread of AR in the context of COVID-19.
