Transfusion Medicine, Tissue Banking, Apheresis, and Coagulation


The Transfusion Medicine Service (TMS) provides medical direction and support for the University of New Mexico Hospital (UNMH), including the blood bank, tissue bank, and apheresis service. Of note, UNMH is the only level-one trauma center in the region. It also serves as the regional burn center, has a kidney transplant program, and houses statewide hemophilia and thrombophilia programs. Transfusion Medicine also supports the National Cancer Institute's designated UNM Cancer Research and Treatment Center, Children's Hospital of New Mexico, and full-service critical care units for all ages. The UNM blood bank transfuses more blood components than any other service in the state. The Special Coagulation laboratory provides a range of coagulation testing ranging from commonplace to esoteric to evaluate: thrombophilia, hemophilia, acquired coagulation defects, and platelet disorders for patients throughout New Mexico. UNMH's Tissue Bank maintains and provides essential tissue products for both inpatient and outpatient surgeries. The TMS service has four board-certified physicians trained in transfusion medicine, who are active in regional and national transfusion medicine arenas, with regular contributions to the scientific literature and textbooks in areas such as perioperative hemostasis, transfusion medicine practice, therapeutic apheresis, and tissue banking.
