French scientists have discovered a new blood type in a woman from the Caribbean island of Guadeloupe, France’s blood supply agency announced Friday.

The woman is the only known carrier of a new blood type, dubbed “Gwada negative,” the French Blood Establishment (EFS) said. The discovery was made 15 years after researchers received a blood sample from a patient who was undergoing routine tests ahead of a surgery.

This woman “is undoubtedly the only known case in the world,” he said, adding: “She is the only person in the world who is compatible with herself.”

    Splitting hairs a bit but if you want to be precise here you need two 'only’s in that sentence, ‘she is the only person whose only compatible donor is herself’.
