The IRR: Helping Labs Test for COVID-19

What is the IRR?

The IRR was established by the Centers for Disease Control and Prevention to distributes COVID-19 diagnostic supplies to registered state and local public health laboratories in the US.

Why was the IRR established?

Testing supplies are distributed by the IRR to:

  • simplify the resource request process for US public health laboratories
  • optimize testing capacity
  • maximize testing using a data-driven algorithm

Who is eligible to order COVID-19 diagnostic supplies through the IRR?

The CDC limits IRR’s SARS-CoV-2 diagnostic reagent distribution to US state and/or local labs qualified to perform seasonal influenza surveillance testing and to local labs approved by their state public health laboratory to perform SARS-CoV-2 testing. Only CLIA facilities with appropriate equipment, training, and demonstration of testing proficiency can be considered.

What does the IRR supply to public health labs?

US public health laboratories can obtain select RNA extraction kits, SARS-CoV-2 RT-PCR kits, enzymes, and consumables from the IRR at no cost. PerkinElmer’s New Coronavirus Nucleic Acid Detection Kit, a real-time RT-PCR test authorized under FDA EUA for the qualitative detection of nucleic acid from SARS-CoV-2, and the chemagic™ Viral DNA/RNA 300 Kit for the extraction of viral RNA are both available for distribution by the IRR. A comprehensive list of all diagnostic testing supplies available through IRR is available here.
