Propel testing excellence with Mayo Clinic quality
Mayo Clinic Laboratories is a one-stop laboratory solution, offering commercial laboratories a vast testing menu, unparalleled customer service, and optimized processes. We work collaboratively with partners to assess their needs, providing the testing they need to expand into new areas and meet their business goals.
As the reference lab for Mayo Clinic, we’ve developed robust logistics and testing protocols applied uniformly for all specimens received, no matter their geographic origin. Whether you send us one test order or thousands, each sample receives the same treatment and level of care, ensuring superior results that help our partners better serve their clients.
“Our clients want personal experiences. They want someone to answer the phone. They want someone to provide answers when they're looking for results of a sample sent a couple days ago. and we deliver those answers.”
Angie Reese-Davis, director of operations, logistics, and specimen services, 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.
The “Reject Due To” information contained in our online test catalog is being updated to provide greater clarity around rejection standards.
The Mayo Clinic Laboratories Education team recently announced the launch of a new educational podcast titled “Lab Medicine Rounds.” Lab Medicine Rounds is a curated podcast for physicians, laboratory professionals, and students that covers a wide variety of laboratory medicine-related topics.
Mayo Clinic Laboratories is thrilled to introduce “Lab Medicine Rounds.” This curated podcast for physicians, laboratory professionals, and students features trending topics from Mayo Clinic Laboratories subject-matter experts.
Newborn screening panels that test for a variety of conditions are available in every state; however, test performance and response rate by each state are very different. Mayo Clinic's Biochemical Genetics Laboratory created the Collaborative Laboratory Integrated Reports tool to mitigate the national (and international) problem of false positives and to raise the bar on test performance.
Traditionally, Mayo Clinic's Simulation Center is used for surgical procedures and teaching students how to run a code. Mayo Clinic pathology consultant Karen Fritchie, M.D., recently developed a new and innovative way to use the center.
In this month’s “Hot Topic,” Curtis Hanson, M.D., will discuss the use of laboratory-based prognostic markers in patients with chronic lymphocytic leukemia (CLL). He will also highlight the importance of molecular analyses for IGHV and TP53 sequencing in these patients.
Ann Moyer, M.D., Ph.D. gives an overview of this new test available through Mayo Clinic Laboratories. She discusses when this testing should be ordered, how this testing improves upon other testing approaches, and what clinical action can be taken due to the results of this testing.
Antimicrobial susceptibility testing determines whether these bacteria are susceptible or resistant to a particular antibiotic. Bacteria are added onto plates of solid agar, where each plate has a different and increasing concentration of antibiotic than the previous plate. The minimum inhibitory concentration (MIC) is the lowest concentration of an antimicrobial that inhibits growth of the bacteria.
David Viswanatha, M.D., a hematopathologist and co-director of the molecular hematology and complete genome sequencing laboratories at Mayo Clinic, provides an overview of BCR/ABL1 testing, discusses the best testing methods, NCCN/ELN criteria guidelines, why FISH testing is no longer routinely available at Mayo Clinic, and what test to order at what time for CML patients.
If your organization refers outpatient testing to Mayo Clinic Laboratories (MCL) for molecular pathology tests, the performing laboratory will be required to bill Medicare directly for tests that meet specific requirements. This new exception to the laboratory Date of Service (DOS) policy will not apply to advanced laboratory diagnostic tests (ADLTs) or molecular pathology tests performed on a specimen collected from a hospital inpatient.
