Ending diagnostic odysseys and inspiring hope
For patients with rare and complex conditions, physicians and other healthcare professionals need trusted answers. Our tests are developed through leading-edge research and unmatched clinical expertise, creating a diagnostics ecosystem that delivers insights that set a new standard in diagnostic care.
Successful patient outcomes are our priority, and we work with hospitals and physicians around the world to elevate diagnostic excellence everywhere. As part of Mayo Clinic’s healthcare system, we understand the best care is provided locally. We complement local expertise by working with clients and logistics organizations to optimize the specimen journey to our laboratories, enabling physicians to get the results they need and patients to remain at home, focused on healing.
Relentless pursuit of answers
Ongoing research propels test development at Mayo Clinic Laboratories, enabling innovative testing that delivers faster, reliable answers to confidently diagnose patients. Our test results not only equip physicians and patients with meaningful diagnostic, prognostic, and therapeutic insights, they also provide hope for a healthier future.
Experience and expertise you can trust
Mayo Clinic Laboratories’ scientists and physicians are leaders in their fields and able to consult on test selection, utilization, and results interpretation. The exchange of knowledge is a founding principle of Mayo Clinic, and we are committed to sharing lessons we’ve learned with our global collaborators through educational opportunities to help improve care delivery in local practices. This is supported through an expansive library of educational content, podcasts, and stories that showcase breakthroughs in test development and perspectives from Mayo Clinic experts.
Access to groundbreaking diagnostics
Driven by an instinct to innovate, we transform scientific discoveries into meaningful advancements in diagnostic testing. Supported by a robust network of Mayo Clinic physicians and scientists and forward-thinking laboratory partners, we foster access to new and advanced testing, much of which is unavailable elsewhere. This integration connects physicians and hospitals around the world with multiple innovative solutions all in one place to support better patient outcomes.
“We treat all of the specimens we receive with the same high degree of care and quality, regardless of where the sample is coming from. We could be testing a sample from a patient that lives in Rochester, Minnesota, or from someone that lives halfway across the world.”
