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.
Jeffrey (Jeff) Meeusen, Ph.D., gives an overview of the new nuclear magnetic resonance (NMR) lipoprotein profile available through Mayo Clinic Laboratories. He discusses when this testing should be ordered, how this testing improves upon previous testing approaches, and what clinical action can be taken due to the results of this testing.
Nikola Baumann, Ph.D., gives an overview of the new NASH-FibroTest available through Mayo Clinic Laboratories. She discusses when this testing should be ordered, how this testing improves upon previous testing approaches, and what clinical action can be taken due to the results of this testing.
Autoimmune neurological disorders can often be treated, sometimes with full restoration of function. However, because the symptoms mimic other conditions, autoimmune neurological disorders are frequently misdiagnosed, resulting in an irreversible loss of function.
A movement disorder might be caused by the body’s immune system, which is meant to fight infections, suddenly attacking the brain. Fortunately, an “autoimmune movement disorder” can often be treated—once its cause is discovered.
After a long wait, the U.S. Food and Drug Administration has finally approved the Elecsys Troponin T Gen 5 STAT blood test. Recently, the Beckman hscTnI assay was also approved. These high-sensitivity troponin assays will benefit emergency departments across the country because the results will allow for earlier and faster recognition of acute myocardial infarction, which interrupts the blood supply to an area of the heart.
Mayo Medical Laboratories, the global reference laboratory of Mayo Clinic, has changed its name to Mayo Clinic Laboratories.
Effective November 9, 2018, our business name will change from Mayo Collaborative Services, LLC, doing business as (d/b/a) Mayo Medical Laboratories to Mayo Collaborative Services, LLC, d/b/a Mayo Clinic Laboratories. The change to Mayo Clinic Laboratories will more accurately reflect the benefit we are able to bring to our clients every day.
Necrotizing autoimmune myopathy (NAM) is a serious but rare muscle disease strongly associated with autoantibodies to either the protein signal recognition particle (SRP) or the enzyme 3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMGCR). NAM typically manifests with subacute proximal limb muscle weakness and persistently elevated serum creatine kinase (CK) concentrations, but slower onsets can occur and complicate diagnosis.
Chromium and cobalt blood tests are used to monitor exposure to these elements. Both of these elements are naturally occurring and widely distributed in the environment. Previously, serum samples were collected and used to monitor patients with metal-on-metal implants, but serum can easily be contaminated during the harvesting and separation of the serum from the cellular blood components causing incorrect results. By using the new EDTA anticoagulated whole-blood test, which is collected in a trace element tube instead of using serum, the risk of contamination is significantly reduced.
Gadolinium-based contrast agents (GBCAs) have revolutionized MRIs by increasing the clinical utility and detection sensitivity of these exams. GBCAs also contain gadolinium, a rare earth metal with unique chemical properties. This article discusses the recent discovery that small amounts of gadolinium remain in human brain tissue following intravenous administration of GBCAs.
In this month’s “Hot Topic,” Brad Karon, M.D., Ph.D., describes how pseudohyperkalemia has many causes, from collection techniques, processing, and even transport. This presentation focuses on the various preanalytic and analytic causes of pseudohyperkalemia and what you as a phlebotomist can do to prevent it.
Many patients may have flare-ups of their disease, or they may stop responding to treatment. In these situations, the clinician may choose to increase the dose administered or recommend more frequent injections. One cause of decreased response to treatment is the appearance of anti-drug antibodies or “immunogenicity.”
