Best Answer

only O negative blood is called the universal donor. This is because people with this blood type have the ability to donate their blood to ANY other blood type. Blood donation is a complex process and only certain types can receive certain types. O neg is the one blood type that can give to anyone (however, they can only RECEIVE from O neg)
