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 research roundup feature: Most patients with solitary bone plasmacytomas (SBP) progress to multiple myeloma (MM) after definitive radiation therapy as their primary treatment. Whether the presence of high-risk (HR) cytogenetic abnormalities by fluorescence in situ hybridization (FISH) in the clonal plasma cells, obtained either directly from the diagnostic SBP tissue or the corresponding bone marrow examination at the time of diagnosis, is associated with a shorter time to progression (TTP) to MM is unknown. This study evaluated all patients diagnosed with SBP at the Mayo Clinic from January 2012 to July 2022.
With all the preparations required to ready a clinical laboratory for regulatory inspection, it can be easy to overlook offsite testing locations, especially those performing CLIA-waived tests. Hospital laboratories with a CLIA Certificate of Compliance or Certificate of Accreditation may also oversee waived testing sites, and it is important to remember that those locations have as much potential for citations as the larger testing departments. Remember to give these five key areas special attention during inspection preparation.
