OBJECTIVE: The need for public health laboratories (PHLs) to prioritize resources has led to increased interest in sharing diagnostic services. To address this concept for tuberculosis (TB) testing, the New York State Department of Health Wadsworth Center and the Rhode Island State Health Laboratories assessed the feasibility of shared services for the detection and characterization of Mycobacterium tuberculosis complex (MTBC). METHODS: We assessed multiple aspects of shared services including shipping, testing, reporting, and cost. Rhode Island State Health Laboratories shipped MTBC-positive specimens and isolates to Wadsworth Center. Average turnaround times were calculated and cost analysis was performed. RESULTS: Testing turnaround times were similar at both PHLs; however, the availability of conventional drug susceptibility testing (DST) results for Rhode Island primary specimens and isolates were extended by approximately four days of shipping time. An extended molecular testing panel was performed on every specimen submitted from Rhode Island State Health Laboratories to Wadsworth Center, and the total cost per specimen at Wadsworth Center was $177.12 less than at Rhode Island State Health Laboratories, plus shipping. Following a mid-study review, Wadsworth Center provided testing turnaround times for detection (same day), species determination of MTBC (same day), and molecular DST (2.5 days). CONCLUSION: The collaboration between Wadsworth Center and Rhode Island State Health Laboratories to assess shared services of TB testing highlighted a successful model that may serve as a guideline for other PHLs. The provision of additional rapid testing at a lower cost demonstrated in this study could potentially improve patient management and result in significant cost and resource savings if used in similar models across the country.
