Origins and development of the National Laboratory System for public health testing.
Although not recognized as such, a National Laboratory System (NLS) has existed since the inception of public health laboratory (PHL) testing more than a century ago. The NLS has always relied upon the participation of clinical laboratories, both to report test results that represent public health threats and to submit specimens and isolates to PHLs for additional or confirmatory testing. Historically, a number of factors have hindered the strengthening of the relationships between clinical laboratories and PHLs, but the reality of bioterrorism and subsequent focus on strengthening public-private relationships has stimulated the development of a more robust NLS. Since 2002, there has been substantial strengthening of the NLS through the sharing of lessons learned from several demonstration projects. There is a growing emphasis on defining critical elements of the NLS, including the State Public Health Laboratory System (SPH Laboratory System) and the functions of the Laboratory Program Advisor, a position that every state should have at the center of its laboratory system's capacity-building. Additional strengthening of the NLS is occurring through (1) national biennial measurement of state PHLs' abilities to meet the Core Functions and Capabilities of State PHLs, (2) the new Laboratory System Improvement Program (L-SIP) for the SPH Laboratory System, and (3) sharing ideas to integrate and improve the SPH Laboratory System (e.g., using the L-SIP Online Resource Center). Public health emergencies, such as the recent H1N1 epidemic, illustrate and reinforce the need for a strong NLS within which federal, public health, and clinical (i.e., hospital and private reference) laboratories function in close collaboration.
