#medtechtrivia Rh null - The "Golden" Blood

Rh null blood is one of the rarest blood type known to man. As its name suggests, this blood doesn’t contain any antigens in the Rh system (D, C, c, E and e). It only occurs in a reported frequency of approximately 1 in 6 million individuals. It’s so extraordinary, in fact, that researchers have only come across 40 or so individuals on the planet who have Rh-null blood. Due to its very limited supply and enormous value, doctors have referred the Rh null as “golden” blood.
