Our extensive test validation includes a breadth of specimens with rare abnormalities. Our laboratories are CLIA-certified and CAP-accredited, and we participate in U.S. and international proficiency programs.
Commitment to education
The exchange of knowledge is a founding principle of Mayo Clinic. In this tradition, we provide a wide range of educational offerings to help our clients increase understanding.
- Regionally based clinical specialists guide best practices through physician education.
- Access to Mayo Clinic Laboratories education and insight articles.
- Many courses offer CME credits.
- Online trainings are available, such as “Dangerous Goods Shipping,” with printable certificates.
Enhanced patient outcomes
Mayo Clinic Laboratories is dedicated to the health and well-being of our patients, which means helping providers deliver care in their local settings through the utilization of our comprehensive subspecialty test menu. Our mission is grounded in our belief that the patient’s needs are paramount, and our clients receive access to:
- Expert-developed algorithms that ensure the right patient receives the right test.
- Testing for rare and complex conditions, with some of that testing exclusive to Mayo Clinic Laboratories.
- Expeditious results due to continuous test processing.
“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.”

In this episode of “Answers From the Lab,” host Bobbi Pritt, M.D., chair of the Division of Clinical Microbiology at Mayo Clinic, and William Morice II, M.D., Ph.D., CEO and president of Mayo Clinic Laboratories, discuss troublesome organisms making headlines.
Nancy Wengenack, Ph.D. gives an overview of this test available through Mayo Clinic Laboratories. She discusses when this testing should be ordered, how this testing compares to other testing approaches, and what clinical action can be taken due to the results of this testing.
This "Phlebotomy webinar" focuses on the origins of difficult collections and the situations that result in them.
In January 2020, Mayo Clinic Laboratories announced one new test along with numerous reference value changes, obsolete tests, and algorithm changes.
At Mayo Clinic, we offer a comprehensive approach to testing that focuses on the best outcomes for the patient. Our testing method combines molecular and cytogenetic analysis (in addition to a standard morphological and histological assessment) to provide a clear picture of the diagnosis, prognosis, and treatment options. This approach maximizes the amount of information available, allowing for a tailored treatment plan.
Autoimmune encephalitis and myelitis is increasingly recognized as a cause of CNS disease in children and teens. Andrew McKeon, M.B., B.Ch., M.D, gives an overview of this test available through Mayo Clinic Laboratories. He discusses when this testing should be ordered, how this testing compares to other testing approaches, and what clinical action can be taken due to the results of this testing.
In this month’s “Hot Topic,” Sounak Gupta, M.B.B.S., Ph.D., discusses selecting tissues and other tissue considerations for molecular testing. He also reviews tissue metrics and requirements, which differ based on test platforms. It is important to keep in mind that the details of tissue metrics change over time as they continue to evolve with technology.
In December 2019, Mayo Clinic Laboratories announced two new tests along with numerous reference value changes, obsolete tests, and algorithm changes.
In this month’s “Hot Topic,” Elitza Theel, Ph.D., talks about Mayo Clinic Laboratories’ serologic and molecular testing for the identification of infection with dengue virus. Dengue virus poses a significant public health threat worldwide. Rapid and accurate identification of the infection enables directed monitoring of patients who may be at increased risk of developing hemorrhagic fever of dengue shock syndrome.
Understanding the difference between benign and malignant adrenal tumors has always been difficult, but the new Urinary Steroid Profile assay will assist with this medical challenge.
In this month’s “Hot Topic,” Elitza Theel, Ph.D., will discuss the over utilization of IgM serologic testing for herpes simplex virus and the recommendation by multiple agencies, including the CDC and the Infectious Diseases Society of America, to avoid using this test for clinical decision making purposes. As a result of these recommendations and data generated at Mayo Clinic, Dr. Theel will summarize why HSV IgM testing will no longer be offered through Mayo Clinic Laboratories.
This week's featured chromosomal microarray test in focus is presented by William Sukov, M.D., a pathologist and cancer geneticist at Mayo Clinic. He discusses when this test should be used for patients with renal tumors.
In this month’s “Hot Topic,” Jessie Swanson and Michelle Soland from the Component Laboratory will discuss the process improvement that helped decrease the standard cryoprecipitate dosage and the positive impact it has on patients.
