Blood Institute

Our Blood Institute (OBI), formerly known as Oklahoma Blood Institute, is one of the largest independent, non-profit blood centers in the United States. The organization provides blood products and specialized services to more than 160 hospitals and medical facilities across Oklahoma, Arkansas, and Texas. Beyond traditional blood collection, OBI operates a robust research division that supports the development of cell-based therapies and provides biological materials for life science research. Through its Bio-Linked platform, the institute connects donors with clinical trials and research projects to advance medical treatments for hematologic and oncological conditions.
