The research team, led by NHS Blood and Transplant (NHSBT) scientists in South Gloucestershire and supported by the University of Bristol, found a blood group called MAL.
They identified the genetic background of the previously known AnWj blood group antigen, which was discovered in 1972 but unknown until now after this world-first test was developed.
Most people are familiar with A, B, O, and Rh red cell antigens, as they are the most significant. Completely separate from this “blood group system” there are many other potentially antigenic molecules present on the red cell membrane.
