Mayo Clinic's Department of Laboratory Medicine and Pathology in Rochester is one of the largest clinical laboratories in the world. It is composed of 1,600 people working in 40 specialty laboratories performing more than 13 million tests a year.

A highly skilled team of medical professionals including physicians, scientists, medical technologists, medical technicians, lab assistants, biologists, chemists, microbiologists, geneticists, and other specialists work collaboratively. The department receives specimens for testing from Mayo Clinic and Mayo Health System and is a reference laboratory for other clinics and hospitals both nationally and internationally.

Mayo Clinic Laboratories is the referral center for Mayo Clinic. Mayo Clinic Laboratories specializes in esoteric laboratory testing for health care organizations throughout the United States and around the world. Mayo Clinic Laboratories' mission is to support the local delivery of laboratory services through the provision of exceptional reference laboratory services and by providing support services that facilitate and augment community integration efforts.

The Division of Anatomic Pathology is comprised of more than 50 pathologists, with subspecialty expertise covering the entire field of surgical pathology. The division is organized around working groups dedicated to specific organ systems, but all members contribute service to general areas as well (such as frozen section lab, autopsy, and cytology, and others).

The division is supported by full-service laboratories in histology, immunohistochemistry, molecular genetics, and cytogenetics. The hospital surgical pathology practice is unique in its heavy reliance on rapid frozen section diagnosis, providing trainees a valuable opportunity for immediate correlation of gross and microscopic pathology. Approximately 80,000 frozen sections are cut annually.

Mayo Clinic processes more than 100,000 surgical cases and 125,000 cytology cases annually; an additional 50,000 consultative cases are referred each year by pathologists from within the United States and around the world. The diagnostic material includes specimens from all fields in pathology.
