Scientists have discovered a new blood group that has so far only been identified in one woman, from the French overseas region of Guadeloupe.
The 68-year-old is the only known person in the world to have this blood group, which has been named "Gwada negative," after a local name for her home islands. The researchers behind the discovery announced their work in a presentation at the International Society of Blood Transfusion’s Congress in Milan, which concluded June 4.
