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.

What is digital imaging?

Digital imaging is the practice of converting glass slides into digital slides that can be viewed on a computer monitor. This digital image is not validated for or intended for diagnostic purposes.

How will I be notified when an image is available?

You can access the image in any of the following ways:

• Set up email notifications so that you receive an email any time a digital image is available.
  • Click the URL in the email to launch the MayoACCESS application.
  • Log in to MayoACCESS. The digital case is displayed.
  • Click the image icon within the case to view the digital slide.
• Set up an unread reports pop-up to be displayed in MayoACCESS when a result with a digital image is attached. Viewing of the laboratory report does not automatically mark it as read. The report needs to be printed or specifically marked as read to prevent the pop-up from being displayed on the next MayoACCESS login.
• When viewing the MayoACCESS laboratory report, the following text and URL are displayed. Click the URL to launch the case view:
