Just as people have different hair or eye color and come in all shapes and sizes, they also have different blood types. While most blood types fall into one of the four major groups: A, B, AB and O, some people have rare blood types. Because of their rare blood types, these patients need a more diverse blood supply.
Red blood cells carry markers called antigens that determine one’s blood type. There are more than 600 known antigens, some that are unique to specific racial or ethnic groups. For example, U-negative and Duffy-negative blood types are two types unique to the African American community. When treating patients who have these rare types, blood from donors of the same ethnic background is less likely to cause complications.
This is especially important for patients who have chronic blood disorders that require regular blood transfusions. Glinda Dames-Fincher, of Mayfield Heights, has lived with sickle cell disease for more than 60 years. Sickle cell disease is the most common genetic blood disease in the U.S. and it largely affects those of African and Latino descent. It causes red blood cells to be hard and crescent-shaped instead of soft and round. As a result, blood has difficulty flowing smoothly and carrying oxygen to the rest of the body. Blood transfusion is a known treatment for patients with sickle cell disease.
“As part of my treatment, I receive monthly red cell exchange transfusions. I receive two pints of red blood cells during each of these transfusions,” said Dames-Fincher. “I have received regular blood transfusions for the last 20 years to help manage my sickle cell disease. Without donated blood, sickle cell patients face sickle cell crisis, and other complications such as strokes, organ failure, chronic wounds, and shortened lifespan.”
The need for blood is constant and all eligible donors are encouraged to give and help meet the need. Whether blood is needed for a chronic condition, such as sickle cell disease, a surgical procedure or a large-scale emergency, it’s the blood already on the shelves that helps save lives.
