Abstract
OBJECTIVES Public health laboratories (PHLs) provide essential services in the diagnosis and surveillance of diseases of public health concern, such as tuberculosis. Maintaining access to high-quality laboratory testing is critical to continued disease detection and decline of tuberculosis cases in the United States. We investigated the practical experience of sharing tuberculosis testing services between PHLs through the Shared Services Project. METHODS The Shared Services Project was a 9-month-long project funded through the Association of Public Health Laboratories and the Centers for Disease Control and Prevention during 2012-2013 as a one-time funding opportunity to consortiums of PHLs that proposed collaborative approaches to sharing tuberculosis laboratory services. Submitting PHLs maintained testing while simultaneously sending specimens to reference laboratories to compare turnaround times. RESULTS During the 9-month project period, 107 Mycobacterium tuberculosis complex submissions for growth-based drug susceptibility testing and molecular detection of drug resistance testing occurred among the 3 consortiums. The median transit time for all submissions was 1.0 day. Overall, median drug susceptibility testing turnaround time (date of receipt in submitting laboratory to result) for parallel testing performed in house by submitting laboratories was 31.0 days; it was 43.0 days for reference laboratories. The median turnaround time for molecular detection of drug resistance results was 1.0 day (mean = 2.8; range, 0-14) from specimen receipt at the reference laboratories. CONCLUSIONS The shared services model holds promise for specialized tuberculosis testing. Sharing of services requires a balance among quality, timeliness, efficiency, communication, and fiscal costs.

Implementation of Salmonella serotype determination using pulsed-field gel electrophoresis in a state public health laboratory. Diagn Microbiol Infect Dis 2016; 85:416-8. [PMID: 27220605 DOI: 10.1016/j.diagmicrobio.2016.04.023] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2016] [Revised: 04/22/2016] [Accepted: 04/23/2016] [Indexed: 10/21/2022]
Abstract
We examined the use of pulsed-field gel electrophoresis (PFGE) to predict serotype for Salmonella isolates. Between 2012 and 2014 we assessed 4481 isolates, resulting in >90% assigned serotypes. PFGE is efficient for determining serotype in the majority of cases and results in expedited serotype determination, as well as cost savings.
