Anyone can receive type O– red blood cells, so people with type O- blood are known

AB+ donors can receive blood from any blood type, so they are called “universal
recipients.” In addition, AB plasma donors can give to all blood types, so AB donors
are called “universal plasma donors.” CR/DRD/I-048 5/24/07
