Digital images for tech-only immunohistochemical (IHC) stains

A comprehensive menu
of IHC stains

Mayo Clinic Laboratories offers pathologists more than 200 IHC stains for technical-only ordering. These stains can be ordered independent of Mayo Clinic pathology consultation, allowing local pathologists the opportunity to review the immunophenotypic profile on a full spectrum of diseases and provide a professional interpretation.

Our large internal practice and extramural consultation services, totaling more than 100,000 cases each year, enables us to validate and offer many cutting-edge and rarely used stains.

If a complex case requires a full consultation, you can request one from one of more than 90 subspecialists at Mayo Clinic Laboratories.
