Lab Capacity: Antibiotic Resistance Laboratory Network (AR Lab Network)

About the AR Lab Network

CDC’s AR Lab Network supports 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 by providing:

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

This infrastructure allows the public health community to:

  • Rapidly detect emerging antibiotic-resistant threats in healthcare, food, and the community
  • Sound the alarm for a comprehensive local response
  • Better understand these deadly threats to quickly contain them

Additionally, some lab samples are made available through the CDC and FDA AR Isolate Bank to support researchers in developing new diagnostics and more treatment options.

Establishing the AR Lab Network

Established in 2016, the AR Lab Network includes labs in 50 states, five cities, and Puerto Rico, including seven regional labs and the National Tuberculosis Molecular Surveillance Center (National TB Center). The National TB Center is coordinated from the state health department in Michigan. The seven regional labs coordinate and complement activities done at the local and state level, and are located in the following state health departments:

  • Maryland
  • Minnesota
  • New York
  • Tennessee
  • Texas
  • Washington
  • Wisconsin

Laboratory tests can help guide patient treatment, detect emerging threats, and prevent the spread of antibiotic resistance. Learn more about the type of AR Lab Network tests on the Laboratory Testing and Resources webpage.

What CDC is Doing

CDC coordinates the AR Lab Network and provides technical expertise. When antibiotic resistance threats are reported, CDC works across the different labs to support outbreak response and create tailored solutions. CDC also adds new isolates to the AR Isolate Bank for drug and diagnostic test development.

The AR Lab Network complements additional CDC antibiotic resistance investments, collectively known as CDC’s AR Solutions Initiative. Through these investments, CDC is transforming how the nation combats and slows antibiotic resistance at all levels.
