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.”

Genome-wide methylation profiling is transforming the way clinicians approach brain tumor diagnosis. By analyzing epigenetic patterns across the genome, this advanced testing method provides a new level of precision, helping resolve ambiguous cases, reduce diagnostic variability, and support more confident clinical decision-making in complex CNS tumors.
In this episode of “Lab Medicine Rounds,” host Justin Kreuter, M.D., speaks with Robert Fazzio, M.D., Ph.D., assistant professor of radiology and chair of the Division of Breast Imaging at Mayo Clinic in Rochester, Minnesota.
In a recent discovery by Mayo Clinic Laboratories, a novel hemoglobinopathy category was identified and termed epsilon gamma thalassemia. The first instance of the disorder was found in 2017 when an obstetric patient underwent a routine screening for blood-related illnesses such as sickle cell disease and thalassemia. Upon completion of additional tests, doctors found an abnormality they had never seen before.
In August of 2021, 28-year-old Mike Knudson, a Twin Cities resident known for his vibrant and active lifestyle, set out on what he anticipated to be an adventurous hiking vacation to the picturesque Glacier National Park in Montana. Little did he know that this journey in nature would be the start of an unexpected life path.
In this episode of “Lab Medicine Rounds,” host Justin Kreuter, M.D., speaks with Allan Jaffe, M.D., Wayne and Kathryn Preisel Professor of Cardiovascular Disease Research, Professor of Laboratory Medicine and Pathology, and Professor of Medicine, in the Department of Cardiovascular Diseases at Mayo Clinic to discuss cardiac troponins and checkpoint inhibitors.
In this episode of “Answers From the Lab,” host Bobbi Pritt, M.D., chair of the Department of Laboratory Medicine and Pathology at Mayo Clinic, is joined by William Morice II, M.D., Ph.D., CEO and president of Mayo Clinic Laboratories. They discuss the U.S. Food and Drug Administration’s (FDA) recently proposed rule that if finalized, would phase out its current enforcement discretion used for laboratory developed tests (LDTs), and regulate all laboratory tests as medical devices regardless of where they are manufactured.

In this month's "Hot Topic," Melissa Snyder, Ph.D., identifies the clinical application of testing for Streptococcus pneumoniae polysaccharide antibodies and describes the tests available for measuring these antibodies.
Mayo Clinic’s cardiac (CV) remote monitoring service uses the compact MoMe Kardia cardiac monitoring device that yields a continuous, 24/7 stream of a patient’s ECG and motion data, no matter their location. Any troubling or burgeoning events are observed virtually the moment they occur, allowing one of Mayo Clinic’s certified rhythm analysis technicians to intervene and facilitate care in near real time. And this is only the beginning; remote patient services are the way of the future, and the future is already here.
Mayo Clinic Laboratories is committed to security and to protecting your information. As part of this commitment, we will implement an optional two-step login process for Mayo Clinic Laboratories applications called Multi-Factor Authentication (MFA). This process is like the two-step login process used by many other apps and provides an extra layer of security.
Marketing is an essential discipline of any successful laboratory outreach program. While specific marketing goals and audiences will differ for every program, most of them will certainly involve driving awareness and growth. A strong partnership with the organization’s marketing team will allow the laboratory to capitalize on the organization’s brand, connect with customers, and generate business. For a busy laboratory, the first step in marketing is often knowing where to focus the team’s valuable resources. Here are some practical marketing strategies any outreach laboratory can apply.
