We are stronger together! Based in Grand Rapids, Versiti Blood Center of Michigan (formerly Michigan Blood) combines the strength of blood centers in Michigan, Wisconsin, Indiana, Illinois, and Ohio with state-of-the-art diagnostic laboratories, physician services, and a world-renowned Blood Research Institute. Your blood will always stay local first, but now we will have even more access to rare and unique blood types to help meet the needs of Michigan hospital patients in need. Together, with you, we promise to continue our mission: we are a beacon of hope.
