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. 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.
