UBC RESEARCHERS MAKE DONATED BLOOD TYPE-O

  Vancouver Sun:  Researchers at the University of B.C. think they may have found a way to transform a very common type of human blood — type-A — in the universally usable type-O negative.

  Because of type-O negative’s universality, it is useful in emergency surgery, for instance, when there isn’t time to test for a patient’s blood type.
  In laboratory tests, the UBC researchers say a “powerful” group of enzymes found in gut bacteria is able to transform type-A blood — both positive and negative — into type-O negative by removing antigens from red blood cells.
