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.”

It’s been more than three years since a team of specialists and genetic testing by Mayo Clinic Laboratories helped pinpoint the cause of Alexa Lofaro’s failing health. And today, she says she continues to feel “so much better” than she did when she first came to Mayo Clinic.
Sean Pittock, M.D., explains how Mayo Clinic Laboratories' novel Ma2 test aids diagnosis of autoimmune neurology disorders that are often caused by underlying cancer. Rapid diagnosis is key to preventing significant disability and disease.
While the accelerated innovation and increased access to testing that’s occurred because of the COVID-19 pandemic has been critically important to worldwide health care, so too has the crash course in laboratory testing and pathology the general public has received throughout the entirety of the pandemic.
Thank you to all laboratory professionals for their efforts to provide critical answers for patients every day, and drive innovation in the field of medicine.
Almost four years ago, Mayo Clinic launched the Digital Pathology Program, a major pathology initiative. Phase 2 of this multi-phase rollout has recently been completed, which involved the implementation of cutting-edge digital equipment and software, and converting glass slides of patient samples into digital images. The conversion enables pathologists and laboratory technologists to view, store, retrieve, and share medical images more universally, without waiting for glass slides to be retrieved and delivered. This has significantly improved patient care because pathologists can now discuss cases with clinicians and surgeons in real time.
In this test-specific episode of the "Answers From the Lab" podcast, Rong He, M.D., explains how Mayo Clinic Laboratories' IDHQ test improves upon next generation sequencing for assessing AML treatment options.
In this episode of “Lab Medicine Rounds,” Justin Kreuter, M.D., sits down with Shane Ferraro, M.H.S., PA(ASCP), an assistant supervisor of pathologists’ assistants in the Division of Anatomic Pathology at Mayo Clinic in Rochester, Minnesota, to talk about the important innovation of 3D scanning in pathology.
