Immunohematology Reference Laboratories
Versiti ensures the provision of antigen-negative and rare units. The Versiti Immunohematology Reference Laboratory is available 24/7 to provide antigen-typed red cells. From our headquarters to our depots, we carry an abundant supply of readily available antigen-negative units. We leverage information on more than 250,000 genotyped donors, the largest known pool of genotyped donors in the United States. This resource allows us to support the vast majority of antigen-negative requests, including rare antigens. In the uncommon event that we cannot fulfill a rare unit request, we seek assistance from the American Rare Donor Program (ARDP).
Medical consultative services are provided by our team of more than 20 highly qualified transfusion medicine specialists, 24 hours a day, 7 days a week. Their expertise and this service transcend all aspects of transfusion medicine, including routine transfusion problems, platelet disorders, bleeding and thrombolytic disorders, transplantation, and therapeutic apheresis. This service is triggered by a 24/7 on-call physician, a rotational responsibility shared within this physician team.
