International Reagent Resources



IRR
Centers for Disease Control and Prevention (CDC) established the International Reagent Resource (IRR) to provide registered users with reagents, test kits, and information for studying and detecting influenza virus and other pathogens, including SARS-CoV-2. Public health labs use these reagents across the globe for the surveillance of newly emerging pathogen strains, such as Influenza (H1N1 and H5N1).
 
Supporting global surveillance of emerging pathogens and emergency response by centralized distribution of diagnostic test kits, ensuring we stay ahead of the next potential public health threat.


IRR has supported the 2009 H1N1 pandemic, the 2015-2017 Zika outbreak, and, most recently, the COVID-19 emergency response.  In early February 2020, IRR joined the emergency response and began supplying US state and local public health labs with EUA-approved COVID-19 diagnostic test kits. By the end of 2021, IRR had distributed over 86,500 COVID-19 related reagents and test kits nationwide, with a catalog expansion from April to December 2020, including numerous commercially produced EUA assays, to provide more products needed for viral testing.

world map imageIRR supports over 800 registered labs across 180 countries and distributes over 1,220 different types of reagents for the detection of influenza, non-flu respiratory viruses,bacterial diseases, and emergency response. The IRR is primarily a resource used to procure pathogen test components and assemble, qualify, and distribute these kits to public health laboratories. This resource supports the detection and characterization of pathogens, which will aid in informing interventions. By centralizing these functions, IRR promotes access and use of these materials in the scientific and public health community and assures quality control of the reagents.

The International Reagent Resource is managed under contract by American Type Culture Collection (ATCC).  Please login to search the catalog for all available items. Scientists must be registered with IRR to request materials.

 

IRR State and Global Public Health Labs
In 2008, CDC established the International Reagent Resource (IRR)--a dynamic and adaptable distribution program that provides reagents, test kits, and information for the detection of influenza and other emerging viral and bacterial pathogens at no cost to registered domestic and international public health labs.
COVID-19 - IRR in Action
 
In early February 2020, IRR joined the emergency response and began supplying US state and local public health labs with EUA-approved COVID-19 diagnostic test kits. To date, the IRR has distributed over 43,000 reagents nationwide, serving as a critical resource to domestic laboratories helping to save lives and protect people,24/7.
