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:

“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.”
