Blood Types Explained | Blood Groups (ABO) and Rh Factor Nursing Transfusions Compatibility
RegisteredNurseRN・13 minutes read
Blood typing involves determining blood groups and the Rh factor before transfusing blood, understanding antigens and antibodies is crucial for blood compatibility, with Type O being the universal donor and AB the universal recipient. Patients with Type A, B, AB, and O have different antigen and antibody profiles, impacting donor and recipient compatibility.
Insights
- Blood typing involves determining blood groups (A, B, AB, O) and the Rh factor (positive or negative) before transfusing blood, ensuring compatibility through understanding antigens on red blood cells and antibodies in plasma.
- Type O is the universal donor lacking antigens, while AB is the universal recipient lacking antibodies, with specific restrictions on transfusions based on blood type antigens and antibodies.

What is blood typing?
Blood typing involves determining blood groups and the Rh factor before transfusing blood.
What is the universal donor blood type?
Type O is the universal donor as it lacks antigens.
What is the universal recipient blood type?
AB is the universal recipient due to no antibodies in plasma.
Can Type A blood receive from Type B donors?
Patients with Type A blood can receive from other Type As, but not from Type Bs or ABs due to antibodies.
Can Type AB blood donate to Type O recipients?
Patients with Type AB blood can receive from all blood types but can only donate to other ABs due to both antigens and antibodies.

Blood typing: Understanding compatibility for transfusions.
- Blood typing involves determining blood groups and the Rh factor before transfusing blood.
- The process includes drawing the patient's blood, determining blood type (A, B, AB, O) and Rh factor (positive or negative), and cross-matching with potential donors.
- Understanding antigens (proteins on red blood cells) and antibodies (found in plasma) is crucial for determining blood compatibility.
- Type O is the universal donor as it lacks antigens, while AB is the universal recipient due to no antibodies in plasma.
- Type A has A antigens and B antibodies, Type B has B antigens and A antibodies, Type AB has both antigens but no antibodies, and Type O has no antigens but both antibodies.
- Patients with Type A can receive from other Type As, but not from Type Bs or ABs due to antibodies.
- Patients with Type B can receive from other Type Bs, but not from Type As or ABs due to antibodies.
- Patients with Type AB can receive from all blood types but can only donate to other ABs due to both antigens and antibodies.
- Patients with Type O can donate to all blood types but can only receive from other Type Os due to both antibodies.
