Blood Transfusion Safety and Risks

Negative side effects of blood transfusion therapy are uncommon. Blood banks, hospitals, and health-care providers take many precautions to minimize risks before each blood transfusion.

Blood banks test each unit of blood to find out its ABO type and Rh status. In the United States, after a hospital laboratory receives a blood unit from the blood bank, the laboratory tests the unit again.
