![]() ![]() Despite this exception, O-negative blood donors (making up only 6-8% of the population) are incredibly important to all blood collection centers. ![]() While O-negative RBCs are ok to give to most patients, I call the term a “misnomer” because we sometimes have to deal with other blood group antibodies (so-called “ unexpected antibodies“) when we are transfusing a patient, so not all O-negative blood can go to all patients (for example, if a patient had anti-K, and the O-negative donor was K-positive, the “universal” donor is suddenly incompatible with that patient). Donors with type O- blood are universal red cell donors whose donations can be given to people of all blood types. Today, in an effort to conserve O negative RBCs, most transfusion services actually use O- positive RBCs for emergency transfusions in males and females who are beyond child-bearing age. For that reason, O-negative red cells were historically given in emergency situations (for example, in patients who have been seriously injured in car accidents or other trauma), before blood banks know the patient’s actual blood type. These donors are considered “universal” because their red blood cells can generally be given to recipients with any ABO type (A, B, AB, or O), and because they are Rh-negative, their blood can be given to either Rh-negative or Rh-positive patients. Stripping Antigens from Donor Lungs Creates Type O. Learn more about how your amazing O positive blood. Each selfless donation makes a huge impact for up to three local patients in need. Type O blood, since it doesnt have antibodies or antigens for either type, can be donated to recipients with all four types of blood. Every 2 seconds, someone in this country needs blood, so your donation is always welcome and sometimes urgently needed. The most common blood type is O positive. The average adult’s body contains between 10 and 12 quarts of blood. It’s awesome and outstanding and so are you. The blood type of a universal donor is O negative, and only about 9 of the population has this blood type. ![]() Approximately 4.5 million Americans undergo blood transfusions annually. This term is a bit of a misnomer, but it is commonly applied to blood donors who have the blood type O-negative. Individuals with Type O-negative blood are universal donors whose blood can be utilised by anyone. ![]()
