O negative
Rare blood type
O negative is a blood type characterized by the absence of A, B, and Rh antigens on red blood cells.
Because it lacks these markers, O negative blood can be safely transfused to patients of any blood type, making it the universal donor blood.
It's the first choice in emergencies when there's no time to determine a patient's blood type: We need O negative—stat!
