Mayo Clinic Laboratories’ expansive clinical specialty test menu — a catalog of more than 3,500 CAP- and CLIA-accredited tests in areas like neurology, oncology, hematology, infectious disease, gastroenterology, and rare disease — propels our laboratory testing services. In addition to offering the world’s largest specialty test menu, we provide access to research-grade tests, pathology services, and sponsored testing programs, availing unparalleled testing expertise to our biopharma partners.

Expert-driven innovation

Our dedicated CAP-affiliated laboratory directors are board-certified physicians and clinical laboratory scientists who engage in clinical practice as well as research. Bringing clinical experience to the test development arena enables evidence-based innovation rooted in patient outcomes. A collaboration with BioPharma Diagnostics provides partners with access to a vast testing library as well as a wealth of patient-centric expertise to optimize clinical trial and drug development.

Our specialty testing areas


BioPharma Diagnostics offers access to some of the world’s most esoteric and advanced neurologic testing. Our assays span the neurologic disease spectrum and include genetic and biochemical biomarker evaluations for Alzheimer’s disease; extensive offerings to evaluate for autoimmune neurologic disorders; next-generation sequencing to identify neurogenetic illness; and other assays.


Mayo Clinic’s extensive oncology test menu features a broad range of biomarker testing to assist with determining diagnosis and treatment effectiveness across the full spectrum of solid tumor malignancies. From single gene and tumor-specific genetic panels to MayoComplete — which evaluates 514 genes — to immunoprofiling, our oncology assays are developed and validated in collaboration with Mayo Clinic oncologists, pathologists, geneticists, and laboratorians.

Infectious Disease

Performing more than 3 million tests annually, our infectious disease and clinical microbiology laboratories have developed and implemented innovative in vitro and culture techniques, immunoassays, antimicrobial susceptibility testing, and molecular models for rapid detection, identification, and characterization of microbes. Our comprehensive testing menu offers a broad selection of tests for rapid identification and in-depth characterization of the causative agents of infectious disease.


With six subspecialty laboratories supporting more than one million annual tests, our hematology laboratories develop, promote, and conduct clinical trial and translational research across the spectrum of hematological conditions. Using state-of-the-art methods, our laboratories provide testing to detect for a range of diseases, including acute leukemias, lymphoid disorders, benign hematology disorders, coagulation disorders, myeloma, and amyloidosis.

Rare Diseases

Affecting 25 to 30 million Americans and manifesting in as many as 7,000 different forms, the cumulative impact of rare diseases is massive. Our genetic testing was developed by geneticists, genetic counselors, laboratory scientists, and bioinformaticians and employs a variety of genetic sequencing techniques to identify and confirm rare disease.


With more than 330 tests in our gastroenterology test catalog, our GI testing plays a key role in establishing Mayo Clinic as the nation’s leading gastroenterology and GI surgery hospital. From routine serological testing to advanced biomarker evaluations, our testing menu offers an array of methodologies to test and guide treatment for GI disorders.
