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.”

News and updates
The latest
In this episode of “Answers From the Lab,” host Bobbi Pritt, M.D., chair of the Division of Clinical Microbiology at Mayo Clinic, is joined by William Morice II, M.D., Ph.D., president and CEO of Mayo Clinic Laboratories, to discuss updates on the Protecting Access to Medicare Act (PAMA) and other policy changes affecting clinical diagnostics. Later, Dr. Pritt welcomes Ann Moyer, M.D., Ph.D., a molecular genetic pathologist at Mayo Clinic and chair of the hereditary genetics practice, to explore how precision therapeutics are improving cancer treatments.
The spectrum of autoimmune movement disorders, diagnosis and treatment.
Anne Tebo, Ph.D., explains how Mayo Clinic Laboratories' updated ALDG2 assay helps with the evaluation of patients with suspected autoimmune liver disease. The panel also helps with the evaluation of liver disease of unknown etiology.
In this episode of “Lab Medicine Rounds,” Justin Kreuter, M.D., sits down with Isabella Holmes, D.O., a first-year pathology resident at Michigan State, to discuss her residency training experience.
VEXAS syndrome is a severe autoinflammatory disease that results in a spectrum of rheumatologic and hematologic conditions. The underlying cause of newly identified VEXAS (vacuoles, E1 enzyme, X-linked, autoinflammatory, somatic) syndrome — somatic mutations in the UBA1 gene of blood cells — was discovered at the National Institutes of Health (NIH) in 2020. Within six months, Mayo Clinic Laboratories was able to add a UBA1 test to the MayoComplete panel, as the team simultaneously worked on a single gene assay to allow doctors to test specifically for UBA1 mutations to screen patients for VEXAS syndrome. The team opted for a droplet digital PCR test — a novel and highly accurate approach to testing for UBA1 gene mutations.
CT scans and hiatal/abdominal ultrasounds could not uncover why, whenever he ate steak, Joseph Ducaji experienced severe stomach problems, itchy hives, chills, and nausea. It took specialized testing from Mayo Clinic to unlock a little-known condition caused by a tick bite (and, no, it’s not Lyme disease).
In this month's "Hot Topic," Bobbi Pritt, M.D., describes the challenges to traditional microscopy for the detection of protozoa in stool specimens, lists potential uses of artificial intelligence in parasite detection, and discusses workflow modifications that may be needed when implementing digital slide scanning and AI-assisted interpretation.
This page includes updates posted to Mayo Clinic Labs during the month of May.
In this episode of “Lab Medicine Rounds,” Justin Kreuter, M.D., sits down with John Mills, Ph.D., associate professor, and vice chair of test implementation for the Department of Laboratory Medicine and Pathology at Mayo Clinic in Rochester, Minnesota, to discuss navigating implementation challenges in the laboratory.
In this month's "Hot Topic," David Murray, M.D., Ph.D., reviews the role of urine testing for monoclonal gammopathies and discusses Mayo Clinic’s use of MASSFIX to replace traditional immunofixation testing.
Due to the Memorial Day holiday (recognized on Monday, May 29), Mayo Clinic Laboratories' specimen pickup and delivery schedules will be altered. To ensure that your specimen vitality and turnaround times are not affected, please plan ahead.
Since March 2019, Paul Jannetto, Ph.D., director of the Metals Laboratory at Mayo Clinic, along with his colleagues across the enterprise and his laboratory staff, have developed, validated, and implemented an artificial intelligence (AI)-augmented test with algorithms designed to interpret kidney stone FTIR spectra. With more than 90,000 kidney stones analyzed each year at Mayo Clinic, this new AI-assisted test has streamlined lab processes and improved patient care.
In this episode of “Lab Medicine Rounds,” Justin Kreuter, M.D., sits down with Bobbi Pritt, M.D., professor and interim chair for the Department of Laboratory Medicine and Pathology at Mayo Clinic in Rochester, Minnesota, to discuss the modern parasitology laboratory.
