Blood Type Chart

A blood type chart is typically used to identify or explain the various types of human blood groups in relation to blood transfusions. It outlines the four main blood types - A, B, AB, and O, along with their Rh factor, either positive or negative. The chart is important because it shows who can donate blood to whom and who can receive blood from whom. It helps to ensure that the right type of blood is given to patients requiring blood transfusions, thus avoiding potentially life-threatening reactions.

In the United States, a blood type chart is typically managed and updated by organizations such as the American Red Cross and healthcare institutions. However, there isn't a specific entity or individual who 'files' a blood type chart. Doctors, clinicians, and healthcare workers rely on these charts for understanding blood types and making decisions about blood transfusions. In Canada, India, and Australia, similar healthcare institutions and blood service agencies handle this information.
