Blood Typing Chart

A Blood Typing Chart is used to identify or classify a person's blood type. Blood type is determined by the types of antigens or markers, present on the surface of red blood cells. The chart typically includes four main blood types: A, B, AB, and O, and their Rh factor (positive or negative). This information is crucial for blood transfusions, organ transplants, pregnancy, and medical research since compatibility between blood types is necessary to prevent negative immune responses.

Blood typing charts are not typically filed by a specific person or organization. Blood typing charts are universal tools used by medical professionals worldwide to understand blood types and their compatibility. They are included in medical textbooks, public health resources, and diagnostic reference guides. Health organizations like Red Cross, hospitals, blood banks, and health departments may have such charts as part of their resources or educational materials. Any changes or discoveries relating to blood types would be documented by research and medical organizations but not by a country or government agency.
