Conversely, AB-positive blood can be donated only to patients with the same blood type, and patients with AB-positive blood are able to receive a transfusion of any blood type, because their immune systems do not generate antibodies to any of the antigens.īeyond these primary eight types, blood comes in more than 600 subtypes, which come into play when transfusions are needed for people with diseases such as sickle cell anemia. Among the eight blood types determined by antigens and Rh, O-negative red blood cells lack the A, B and Rh antigens and can be donated to a person with any blood type. A transfusion of blood with a positive Rh factor will generate an immune response in a person who is Rh negative, but the reverse is not true. In addition, each blood type comes in two subtypes based on the presence or absence of a protein antigen called the Rh factor. The A antigens cause a person’s immune system to produce antibodies against the B antigens, and vice versa, meaning that a person with Type A blood will have a potentially fatal reaction to a transfusion of B red blood cells. Human red blood cells come in four major types - A, B, AB and O - based on the presence or absence of A and B antigens on the cell surface. Type AB blood cells have both A and B antigens.

The antigens on Type A and B blood cells are made up of this base antigen plus one additional sugar. Recent work by researchers at the University of British Columbia using enzymes from human gut bacteria to modify A and B red blood cells may bring us closer to the solution.Īlthough they are sometimes referred to as “naked,” Type O blood cells have a base oligosaccharide antigen. One step toward addressing the shortage of O-negative blood may be to convert other types of blood to O. population has Type O-negative, which is used by hospitals in almost all emergency surgeries and traumas that require transfusions. Meanwhile, blood suppliers face a near-constant shortage of universally acceptable O-negative blood. Experts say all this does not bode well for the industry as a whole. According to Red Cross officials, they already have reduced staff and donor-recruitment efforts. In August, the American Red Cross - the country’s largest blood supplier, providing around 40 percent of the blood used in hospitals - announced that it would need to raise the price of the blood it sells to hospitals to cover its operating costs.

While this has cut costs for hospitals, insurance providers and patients, it has upended the nonprofit business model of blood suppliers in the United States.

What is your blood type? Donate and find out.Over the past decade, the amount of blood transfused in the United States has plummeted due to improved patient management and strategic scheduling of elective surgeries. Nearly 16 million blood components are transfused each year in the U.S.' For more about plasma donation, visit the plasma donation facts. The universal plasma donor has Type AB blood. The universal red cell donor has Type O negative blood. The need for O+ is high because it is the most frequently occurring blood type (37% of the population). However, the need for O negative blood is the highest because it is used most often during emergencies. Only 7% of the population are O negative. Types O negative and O positive are in high demand. Minority and diverse populations, therefore, play a critical role in meeting the constant need for blood. Type O is routinely in short supply and in high demand by hospitals – both because it is the most common blood type and because type O negative blood is the universal blood type needed for emergency transfusions and for immune deficient infants.Īpproximately 45 percent of Caucasians are type O (positive or negative), but 51 percent of African-Americans and 57 percent of Hispanics are type O. Why? O negative blood can be used in transfusions for any blood type. Universal donors are those with an O negative blood type.
