1 The Laboratory Response Network

2 LRN Structure for Bioterrorism
What Is the LRN? A Diverse Laboratory Network National network of local, state and federal public health, hospital-based, food testing, veterinary and environmental testing laboratories that provide laboratory diagnostics and the capacity to respond to biological and chemical terrorism and other public health emergencies. Multi-agency collaboration The LRN is a partnership involving key stakeholders in the preparation and response to biological and chemical terrorism. The Centers for Disease Control and Prevention (CDC), the Federal Bureau of Investigation (FBI), and the Association of Public Health Laboratories are its founding partners. LRN Structure for Bioterrorism

3 LRN Mission The LRN and its partners will maintain an integrated national and international network of laboratories that can respond quickly to acts of chemical or biological terrorism, emerging infectious diseases and other public health threats and emergencies. Our Mission in Action Bioterrorism Preparedness Timely detection of Bacillus anthracis during anthrax attacks in 2001 BioWatch Public Health Emergency Response Developed rapid tests for detection of Severe Acute Respiratory Syndrome Monkeypox Talking Points: About LRN Mission LRN Mission Statement succinctly answers the question: What is the LRN? Mission statement highlights three key goals of the LRN: Continued development of its laboratory network by supporting existing members and expanding its membership base; Capacity building, and; Nurturing its partnerships. “IT IS NOTEWORTHY TO POINT OUT THAT THE LRN’S MISSION REFLECTS A PUBLIC HEATLH FOCUS BEYOND CHEMICAL AND BIOLOGICAL TERRORISM AND THAT THE LRN RESPONDS TO OTHER PUBLIC HEALTH CONCERNS.” “OUR MISSION IS EVIDENT IN SOME OF OUR RECENT PUBLIC HEALTH EMERGENCIES.” During the course of the 2001 anthrax investigation, the LRN labs tested more than 125,000 samples, representing about 1 million tests. Select LRN labs are participating in surveillance for environmental exposures using air samplers. These labs are testing the filters from the air samplers daily for biological agents. Currently, LRN is helping to develop tests and reagents used to detect coronavirus.

4 The Laboratory Network
Talking Points: The foundation of the LRN is its member laboratories. Points on the map represent both reference and national labs. National labs represent the CDC and US Army Medical Institute of Infectious Diseases (USAMRIID) at Fort Detrick, MD. Reference labs are state and local public health labs, and some military labs. The goal is to have at least one BSL3 lab in each state. LRN is working to establish relationships with private and commercial labs, totaling about 2,500, to act as sentinel labs capable or performing preliminary tests and shipping samples to appropriate reference labs for confirmatory testing. There is also a potential for sentinel labs to handle surge in case reference labs become overwhelmed. This structure is designed to enhance the public health infrastructure by integrating the expertise and capacity of labs nationwide and globally. Rather than a few labs performing rapid lab testing, more labs are capable of such testing in the event of an outbreak. WHAT FOLLOWS IS AN ILLUSTRATION OF GEOGRAPHICAL COVERAGE AND WHERE STATE, LOCAL, FEDERAL, INTERNATIONAL AND MILITARY LABS ARE LOCATED More than 140 federal, state and local labs in 50 states and abroad National labs – CDC, military – perform definitive testing. Reference labs – BSL-3 labs capable of confirmatory testing for agents such as B. anthracis, and C. botulinum toxin.

5 Partnerships Founding Partners CDC
Association of Public Health Laboratories The Federal Bureau of Investigation Talking Points: THE LRN SLOGAN IS “PARTNERS IN PREPAREDNESS.” PARTHERSHIPS DRIVE THE ORGANIZATION. OUR FOUNDING PARTNERS, FOR EXAMPLE, EACH BROUGHT THEIR UNIQUE STRENGTHS AND PERSPECTIVES THAT HAVE HELPED SHAPE THE LRN INTO WHAT IT IS TODAY: CDC-Expertise in handling virulent agents, developing clinical assays, investigating outbreaks of disease, and coordinating development and operation of the LRN; APHL—Membership that allows for broad coverage. APHL also coordinates state and local public health labs for the LRN; FBI – Helped shape chain of custody policies to protect the integrity of criminal investigations amidst often opposing public health investigations.

6 Partnerships Shape the Scope of the LRN
International Laboratories – LRN membership includes labs in Australia and Canada; Environmental – LRN is working with EPA to build testing capacity for measuring biological and chemical agents in environmental samples. Food and Water – LRN includes food and water testing labs to guard against contamination Veterinary labs –The National Animal Health Laboratory Network through USDA’s Animal and Plant Health Inspection Service (APHIS), and the American Association of Veterinary Laboratory Diagnosticians LRN partnerships extend beyond its original founding partners. Relationships with federal agencies, such as the EPA, FDA and USDA, are helping to establish preparedness and response policies to protect food and water supplies, guard against chemical exposures and monitor animal populations that are often the first sign of a disease outbreak. VDL’s may be joining the LRN to serve as Reference Labs under the USDA gatekeeper.

7 Structure for Bioterrorism Response

8 National Laboratories
National laboratories, including those operated by CDC, are responsible for specialized strain characterizations, bioforensics, select agent activity, and handling highly infectious biological agents and toxic chemicals.

9 Reference Labs Reference laboratories - responsible for investigation and/or referral of specimens --are made up of more than 140 state and local public health, military, federal, and international laboratories. Lab types include veterinary, agriculture, food and water testing laboratories. In addition to laboratories located in the U.S., facilities located in Australia, Canada, and the United Kingdom serve as reference laboratories abroad.

10 Sentinel Laboratories
Sentinel laboratories provide routine diagnostic services, rule-out and referral steps in the identification process. Although these laboratories may not be equipped to perform the same tests as LRN reference laboratories, they can test samples to determine whether those samples should be shipped to reference or national laboratories for further testing.

12 Structure for Chemical Terrorism Response

13 Chemical Testing Capacity
Level 3 62 Labs Competency in collecting and shipping clinical samples Comprehensive response plan Level 1 5 Labs Level 2+ Level activities Mustard Agents Nerve Agents Level 2 41 Labs Level 3 Activities Cyanide Toxic Metals CDC

14 LRN Structure—Chemical Terrorism
Currently, 62 state, territorial, and metropolitan public health laboratories participate in the chemical portion of the LRN. A designation of Level 1, 2, or 3 defines member network participation, and each level builds upon the preceding level. Every network member participates in Level 3 activities. These Level 3 laboratories work with hospitals in clinical specimen collection, storage, and shipment. They also work to develop a coordinated response plan for their state and geographical regions.

15 LRN Structure—Chemical Terrorism
Forty-one labs also participate in Level 2 activities; they are trained to detect exposure to a limited number of toxic chemical agents. Detection of toxic chemicals, such as cyanide or toxic metals, present in human specimens is an example of Level 2 laboratory analysis. Five laboratories participate in Level 1 activities, and these laboratories are trained to detect exposure to an expanded number of chemicals including all Level 2 laboratory analyses plus analyses that indicate exposure to mustard agents, nerve agents, and ricin.

16 Preparing to Respond to a Chemical Event
CDC is assisting LRN Labs by Purchasing instrumentation Developing training curricula Transferring analytical methods Implementing a quality assurance program CDC has assisted with purchasing the instruments needed for measuring chemicals in blood and urine to LRN members and is also transferring analytical methods to Network members. Those laboratories that receive methods and instrumentation must participate in a rigorous quality assurance program to ensure that network labs provide precise, accurate, high-quality data. In an effort to create a skilled workforce, CDC has developed training curricula for network members. This “train-the-trainer” program will give chemical terrorism coordinators information so that they can train hospitals in their jurisdiction.

17 Rapid Toxic Screen At the onset of an event, a state may request CDC’s assistance. CDC will deploy a Rapid Response Team to the affected state to assist with specimen collection, packaging, storage, and shipment. The first 40 samples from people with symptoms are sent to CDC for analysis through the Rapid Toxic Screen, which can analyze people’s blood and urine for a large number of chemical agents likely to be used by terrorists. Data produced from the Rapid Toxic Screen analysis will be communicated in a secure, electronic manner to the affected state or states.

18 Responding to a Chemical Event
Incident CDC Sends Results to State LRN Members Perform Level-Specific Duties and Report Results Back to CDC State Requests CDC Assistance CDC Contacts LRN Members Rapid Response Team Deploys At the onset of an event, a state may request CDC’s assistance. CDC will deploy a Rapid Response Team to the affected state to assist with specimen collection, packaging and/or storage, and shipment. The first 40 representative samples from people with symptoms are sent to CDC for analysis through the Rapid Toxic Screen, which can analyze people’s blood and urine for a large number of chemical agents likely to be used by terrorists. Data produced from the Rapid Toxic Screen analysis will be communicated in a secure, electronic manner to the affected state or states. Hospitals and laboratories may be inundated by people concerned about exposure. There will be a need to respond to these concerns and to determine whether an individual has been exposed and at what level. CDC will contact the appropriate network laboratories, and these laboratories will contribute to the response depending on their level of network participation. All results will be sent to CDC and CDC will share results with the affected state or states. CDC Conducts Rapid Toxic Screen CDC Sends Results to State
