Video available at: http://vimeo.com/52548635 8  Public Health Laboratories Working in collaboration with other arms of the nation’s public health system, PHLs provide clinical diagnostic testing disease surveillance advanced skills in laboratory practice Photo: James Gathany, CDC 9 The Goal of Public Health Laboratories The goal of public health laboratories is to protect and improve public health by testing samples providing expertise communicating scientific information 10  Clinical Laboratories versus Public Health Laboratories Clinical Laboratories — Public Health Laboratories — Individual Health Population Health Diagnostic testing Some diagnostic testing Some reference testing Reference testing Medical management Surveillance and monitoring Emergency response support Applied research Workforce development and training 11 Newborn Screening Newborn screening is an example of one of the many functions that a public health laboratory performs 12  Knowledge Check Which of the following are activities and services performed by public health laboratories? (Select all that apply) A. Conducting blood tests as part of the ongoing management of a patient’s disease B. Testing samples collected during a disease outbreak C. Providing screening for all newborns D. Training public health laboratory personnel 13  Knowledge Check Which of the following is the best example of what public health laboratories do as opposed to clinical laboratories? A. Cholesterol screening B. Diagnostic testing C. Routine blood testing D. Disease surveillance 14  Topic 3 Core Functions of State Public Health Laboratories Photo: James Gathany, CDC 15  Core Functions of State Public Health Laboratories Eleven core functions have been established by the Association of Public Health Laboratories, or APHL, to provide a basis for assessing and improving the quality of laboratory activities being conducted Photo: CDC 16  Core Functions of State Public Health Laboratories Core Functions 1–3 1.

Hypothyroidism 21  Knowledge Check Eleven core functions have been established by the Association of Public Health Laboratories, or APHL, to provide a basis for _________ and _________ the quality of laboratory activities being conducted A. assessing, maintaining B. assessing, improving C. maintaining, standardizing D. Improving, standardizing 22  Topic 4 Public Health Laboratory Infrastructure 23  PHL System Infrastructure Environmental laboratories Federal public Physician State PHL health laboratories laboratories Local public health Clinical departments laboratories and laboratories 24  PHL System Infrastructure (continued) Environmental laboratories Federal public Physician State PHL health laboratories laboratories Local public health Clinical departments laboratories and laboratories 25  PHL System Infrastructure (continued) Perform tests on behalf States and Territories of the jurisdiction Becomes involved when Federal additional assistance is needed Focuses on testing samples of air, food, soil, water, Environmental and zoonotic-related illnesses Identifies initial cases Private (physician associated with an or clinical) outbreak 26  Knowledge Check Which laboratory serves as the center of the public health laboratory system infrastructure? A. Local public health laboratories B. State public health laboratories C. Federal laboratories D. Private clinical laboratories 27  Knowledge Check In the event of a salmonellosis outbreak, what role might a federal laboratory perform? A. Collect specimens required for testing B. Send specimens to clinical laboratories for confirmation of initial findings C. Confirm cases through testing D. Provide guidelines and recommendations for testing Salmonella bacteria 28  Topic 5 Laboratory Safety 29 Laboratory Safety Overview Each laboratory must have key safety principles and procedures in place that minimize the risk for contamination and exposure to the pathogens being tested 30 Laboratory Biosafety Levels In biologic laboratories, one of four biosafety levels are assigned, with Level 1 being the lowest risk and Level 4 the highest 31  Laboratory Safety Governance Federal Entities Occupational Safety and Health Administration (OSHA) Clinical Laboratory Improvements Amendments (CLIA) U.S. Department of Agriculture (USDA) U.S. Department of Justice (DOJ) U.S. Environmental Protection Agency (EPA) Food and Drug Administration (FDA) Centers for Disease Control and Prevention (CDC) National Institutes of Health (NIH) 32 Laboratory Safety Considerations What type of samples to collect What method(s) to use to collect the samples How to store the samples Which laboratory can receive and test the samples How to pack, label, and ship the samples 33 Shipping Samples Before shipping samples, determine if the specimen is appropriate for the designated PHL identify correct packing and shipping techniques ensure specimens have correct documentation and labels 34  Knowledge Check True or false? Safety principles and practices are the same for all laboratories. A. True B. False 35  Topic 6 Using Results To Affect Public Health 36 Electronic Laboratory Reporting (ELR) Laboratory Response Network (LRN) Food Emergency Response Network (FERN) PulseNet 37  Using PHL Results After public health data from ELRs are collected and disseminated, data are used to monitor trends and detect changes, identify or confirm an outbreak, provide guidance and immediate action, guide public policy, determine disease history, prioritize resource allocation, provide a baseline for epidemiologic research, and identify environmental hazard and exposures 38  Knowledge Check Which of the following describe how public health laboratory data are used to affect public health? A. Guide public policy B. Determine disease history C. Detect changes D. All of the above 39  Course Summary During this course, you learned to describe the role of public health laboratories summarize the core functions of state public health laboratories describe the parts that are common to all public health laboratory system infrastructures recognize the need for different laboratory levels and safety practices explain the necessity for communicating with a laboratory when collecting and submitting samples for testing describe how laboratory results are used to affect public health 40  Resources and Additional Reading Centers for Disease Control and Prevention.
