The rarest blood type in the world is Rh-null, also known as golden blood. It's so rare that there are fewer than 50 known individuals with this blood type worldwide. People with Rh-null blood lack all Rh antigens on their red blood cells. This makes their blood incredibly valuable for transfusions, as they can donate to anyone with any Rh blood type. However, they can only receive blood from other Rh-null individuals, making them highly vulnerable in emergencies.
- Rh-null is considered "golden blood" due to its extreme rarity and its potential to save lives.
- People with Rh-null blood have no Rh antigens on their red blood cells, which makes their blood universally compatible for transfusions.
- Despite its lifesaving potential, individuals with Rh-null blood can only receive blood from other Rh-null donors.
