Transfusion Medicine Fellowship

The UT Health San Antonio offers a one-year Transfusion Medicine Fellowship that is fully accredited by the ACGME. The fellowship accepts one trainee per academic year with a structured curriculum and dedicated teaching staff. During training, the fellow receives training in immunohematology, histocompatibility, paternity testing, donor center supervision, therapeutic apheresis, transfusion therapy, hemostasis, flow cytometry, and molecular pathology. The training is based upon participation of daily activities, consultations, various elective experiences as well as didactic teaching.
