The group is recognized for developing standards to improve the decision-making process and response to biological threat agents by first responders. The suite of standards include standard methods for powder collection, operational guidelines for first responders, and the first NIST live cell reference material. The suite of standards has been refined in field and interlaboratory studies with professional rescue personnel. These efforts have strengthened the national biothreat response and increased quality of results used to support high-stakes public safety decision-making.
