ARUP Building


Rather than competing with its clients for physician office business, ARUP chooses instead to support clients’ existing test menus by offering highly complex and unique lab tests, with accompanying consultative support, to enhance their abilities to provide laboratory services.

We position our clients to succeed and lead the way in transitioning to a value-based healthcare model that shapes the full-spectrum of UM+ strategies and tools we’ve developed. Relying on our time-honored expertise, we’re empowering our clients with the most current testing knowledge, highly customized analysis, and unparalleled guidance in implementing these tools to attain results.


ARUP's clients include more than half of the nation's university teaching hospitals and children's hospitals, as well as regional hospital networks, multihospital groups, major commercial laboratories, group purchasing organizations, military and government facilities, and major clinics.

Since its formation in 1984 by the Department of Pathology at the University of Utah, ARUP has founded its reputation on reliable and consistent laboratory testing and service, a simple strategy that contributes significantly to client satisfaction. When ARUP conducts surveys, clients regularly rate ARUP highly and respond that they would recommend ARUP to others.

Technical Services

ARUP's comprehensive clinical and anatomic pathology test menu includes the areas of allergy and immunology, chemistry, cytogenetics, endocrinology, fetal risk assessment, genetics, hematology, hepatitis and HIV, infectious diseases, neurology, oncology, and pathology. ARUP performs 99 percent of all testing on-site, operating 24 hours per day, seven days a week, and processing approximately 55,000 specimens of blood, body fluid, and tissue biopsies per day.

ARUP provides some of the best turnaround times available in the industry, due in part to the advanced instrumentation and automated systems used in specimen receiving, tracking, and retrieving. Test results are also rapidly delivered to clients through customized information systems.

Additionally, ARUP is a worldwide leader in innovative laboratory research and development, led by the efforts of the ARUP Institute for Clinical and Experimental Pathology®.

Trusted Pathologists

ARUP’s esoteric tests complement the resources of its clients. Medical consultation is provided by some of the most highly regarded medical professionals in the industry, and through a disease-management approach (including clinical algorithms), testing is identified that most appropriately monitors disease progression and therapy after diagnosis. Medical directors and genetic counselors are available for consultation and result interpretation.

Esoteric testing, medical consultation, and disease management are just some of the ways ARUP enables clients to meet today’s challenges. With a focus directed toward the future and its many possibilities, ARUP is committed to keeping abreast of new technologies, original research, and innovative ways to improve testing within the modern health care environment. Together, ARUP and its clients will improve patient care today and in the future.
