What is a blood type table used for?

A blood type table is a chart that shows the different blood types and their compatibility for blood transfusions. It is used to determine which blood type can safely be transfused into a patient based on their own blood type.

The table lists the different blood groups (A, B, AB, and O) and Rh factors (positive or negative) and indicates which blood types are compatible with each other for transfusions. For example, a patient with A-positive blood can receive blood from donors with A-positive, A-negative, O-positive, and O-negative blood types.

Blood type tables are essential in transfusion medicine to ensure that patients receive compatible blood transfusions and avoid potentially life-threatening complications such as transfusion reactions. They are used by healthcare professionals in hospitals, clinics, and blood banks to make informed decisions about blood transfusions.
