Updated on November 6 

Over the next several weeks, our valued clients will see the gradual implementation of our new brand name. Effective November 9, 2018, our business name will change from Mayo Medical Laboratories to 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, by letting them know that the expertise and teamwork of Mayo Clinic is behind each of our laboratory tests. We take pride in our ability to deliver more than just test results and be able to provide real answers for your patients, their families, and physicians.

  • You may need to update your systems and records to match the new business name.
