Blood & Marrow

Allogeneic Blood and Marrow Transplantation

Allogeneic transplantation is a procedure in which a person receives hematopoietic (blood-forming) or blood stem cells, from a genetically similar, but not identical, donor.

Alpha Thalassemia

Thalassemia is an inherited disorder that affects the production of normal hemoglobin (a type of protein in red blood cells that carries oxygen to the tissues of the body).

Anemia (hemolytic)

Hemolytic anemia is a disorder in which the red blood cells are destroyed faster than the bone marrow can produce them.

Anemia (megaloblastic or pernicious)

Megaloblastic anemia is a type of anemia characterized by very large red blood cells. In addition to the cells being large, the inner contents of each cell are not completely developed.

Anemia (aplastic)

Aplastic anemia occurs when the bone marrow produces too few of all types of blood cells: red cells, white cells, and platelets. 

Beta Thalassemia (Cooley's Anemia)

Thalassemia is an inherited disorder that affects the production of normal hemoglobin (a type of protein in red blood cells that carries oxygen to the tissues of the body). Thalassemia includes a number of different forms of anemia.

Blood Stem Cell Collection

Peripheral blood stem cell (PBSC) collection is a procedure where volunteer donors (relatives or siblings) or patients donate their stem cells through apheresis for allogeneic and autologous blood and marrow transplantation.

Blood Transfusion

More than 2,700 patients receive blood transfusions each year at Children’s National Health System’s hospital and Regional Outpatient Centers, including approximately 7,500 red blood cell, 2,000 plasma, 3,000 platelets, and 900 cryoprecipitate units.
