University Of Wisconsin System

University of Wisconsin System, Wisconsin State Laboratory of Hygiene Division (doing business as Tandem Press), a state government laboratory operating as a division of a 1862 land grant public university system, delivers specialized laboratory testing, analytical services, and diagnostic support to federal agencies as a prime contractor on 169 awards (93% of footprint) and as a sub-awardee on 12 federal grants. The division operates without SBA set-aside designations and competes full-and-open across all customer agencies.

The laboratory's capability portfolio centers on three core service areas: cytogenetic reference testing and diagnostic support for veteran patients; water contamination analysis and environmental monitoring (PFAS, benzotriazoles, and atmospheric deposition); and proficiency testing and quality assurance for clinical and public health laboratory operations. Representative prime work includes a $1.0 billion IDIQ awarded by the Department of Veterans Affairs on February 1, 2026 for cytogenetic reference laboratory services at William S. Middleton VA Medical Center in Madison, Wisconsin, with an initial delivery order valued at $181,615.10 for cytogenetic diagnostic services through January 31, 2027. The division holds a single-award Blanket Purchase Agreement worth $150,000 (through September 2028) with the Department of the Air Force for newborn metabolic screening test services at Spangdahlem Air Base in Germany. A $245,789.79 definitive contract modification (awarded April 5, 2024) extends the laboratory's participation in the National Atmospheric Deposition Program/National Trends Network through March 31, 2029, exercising an optional second-year option for water sample analysis and atmospheric deposition monitoring. Additional recent awards include a $275,100 purchase order from CDC Pittsburgh (June 2026) for Lead and Multi-Element Proficiency (LAMP) testing services through March 2031, and multiple Department of the Interior delivery orders for water quality assessments supporting the Great Lakes Science Center and USGS environmental programs.

Customer concentration is moderate and distributed across clinical and environmental missions. The Department of Veterans Affairs Veterans Integrated Service Network 12 dominates both award count and potential value (23 awards, $2.3 million), driven by recurring cytogenetic laboratory delivery orders. The Department of Health and Human Services — Centers for Disease Control and Prevention accounts for $1.6 million across 10 awards (Pittsburgh location) and $1.1 million across 5 awards (Office of Acquisition Services), making CDC the second-largest customer by dollars. The Department of the Interior entities (USGS Office of Acquisitions and Grants and Fish and Wildlife Service) together account for $987 thousand across 20 awards, primarily water contamination and environmental monitoring work. The top five customers represent 71% of combined potential value and 37% of award count, indicating concentration among a small number of federal agencies with recurring laboratory service needs.

The division holds three single-award IDIQs: the $1.0 billion VA contract for cytogenetic services (February 2026, through January 2031), a $217,150 USGS water contamination testing IDIQ (March 2022, expired March 2024 in source data), and a $150,000 Air Force Blanket Purchase Agreement for newborn screening (September 2023, through September 2028). Task-order activity on named parent vehicles shows the laboratory issuing 7 task orders under IDV 36C25220D0033 ($241 thousand), 6 under IDV 140G0222D0004 ($135 thousand), and 6 under IDV VA69D15D0069 ($199 thousand), indicating steady utilization of standing agreements across VA and interior agency vehicles.

Award activity has remained consistent over the past five years (2022: 10 awards, 2023: 7 awards, 2024: 10 awards, 2025: 7 awards, with 3 awards in 2026 year-to-date). Recompete exposure in the next twenty-four months is minimal — only 2 awards totaling $232 thousand face ultimate completion dates within that window. The laboratory's combined potential value across the 181-award footprint stands at $8.4 million, with $15.1 million in obligated dollars, indicating high utilization of standing contract capacity.

The Service Contract Inventory dataset captures minimal activity: 3 SCI records spanning FY2022–FY2024, with zero prime invoiced revenue reported and 0.6 FTEs appearing in one sub-awardee record in FY2024. This reflects the laboratory's structure as a state-controlled institution; SCI reporting captures only federal service contracts above $150,000 threshold and excludes educational institution grant work and goods contracts that dominate the division's actual federal footprint. The laboratory acts primarily as direct prime contractor (93% of awards), with limited subcontractor engagement across SCI-reportable work (0% sub-hours share on prime contracts).

Grant sub-awardee work routes through the Association of Public Health Laboratories and the State of Wisconsin Department of Health Services as prime grantees. Notable sub-award work includes participation in seasonal and summer operations for the National Influenza Reference Center (July 2024, May 2024), pilot implementation of spike gene sequencing assay for SARS-CoV-2 (December 2024), and vaccine preventive disease testing and proficiency panel services (August 2025). A Georgia Tech Research Corporation sub-award (October 2023) involved testing novel influenza vaccines for immunogenicity and protective efficacy, and a second Georgia Tech sub-award (April 2025) supported biomarker and statistical analysis for an implant skin dehiscence study.

The laboratory's footprint reflects a specialized public health and clinical testing mission serving federal healthcare (VA), environmental science (USGS, Fish and Wildlife), and public health agencies (CDC, Indian Health Service) without private-sector competition positioning or commercial revenue diversification. Work is performed at the laboratory's Madison, Wisconsin facility with overseas support at Spangdahlem Air Base, Germany.
