Honors and Recognition
The following organizations have honored Mayo Clinic and Mayo Medical Laboratories:
Championing Community-Based Medicine

Whenever possible, patients should receive testing within their local communities. Since our inception in 1971, we have collaborated, not competed, with our laboratory partner organizations. Through strategic collaborations, we work closely with our laboratory partners to build and sustain outreach activities, provide esoteric and specialty testing, and position our community laboratories as the centers of excellence in their respective communities.
- Supporting Patient Care Activities Worldwide
Through partnerships with worldwide logistics providers and advanced specimen-packaging technologies, we support patient-care activities on nearly every continent. We work closely with each health care organization to meet its specific testing needs.
- Strengthening Community-Based Laboratories Through Outreach Support
We strongly believe in the role of laboratory outreach and its ability to improve patient care within a community. That is why we are the only major reference laboratory with dedicated outreach support staff to help our partner institutions develop and strengthen laboratory outreach programs.
- Enabling Access to Specialty Testing with Our Partners
Adverse to the industry trend of cutting out community hospitals and going directly to physicians, we partner with community laboratories to support their specialty care clinics by offering a comprehensive joint-test menu that supports local cardiologists, hematologists, neurologists, and oncologists.
