Diagnostic Lab of Michigan

We are pleased to announce that Quest Diagnostics and Corewell Health, a leading health system, are forming a multi-faceted collaboration to broaden access to innovative, high value laboratory services for you and other providers in Michigan.

Specifically, Quest Diagnostics and Corewell Health have entered into a definitive agreement to form a joint venture (JV), named Diagnostic Lab of Michigan, that will feature a new state-of-the-art laboratory built in Southfield, Michigan.

This new joint venture laboratory will allow us to bring more innovative and, in many cases, more affordable lab services to our patients while also continuing to provide high quality care.

The Diagnostic Lab of Michigan will not be fully operational until the beginning of 2027.

For now, there are no changes to current processes; at this time, please continue to order laboratory services from Quest Diagnostics and Corewell Health as you normally would.

Your representatives from Quest and/or Corewell Health will continue to support you and keep you updated throughout the development of the new joint venture laboratory. We are committed to a smooth transition and are confident that Diagnostic Lab of Michigan will be well positioned to deliver superior lab services to you and your patients.
