The gold blood type, also known as Rh-null, is the rarest blood type in the world, with fewer than 50 people confirmed to have it. Individuals with this blood type lack all 61 possible Rh antigens on their red blood cells.
This makes Rh-null blood universally compatible with all Rh-negative blood types. However, it's crucial for people with Rh-null blood to only receive transfusions from other Rh-null donors, as receiving any other type of blood could trigger a severe immune response.
The rarity of Rh-null blood has led to its nickname "golden blood," signifying its value and the potential for life-saving transfusions.
- Unique Characteristic: The absence of Rh antigens on red blood cells.
- Rarity: Fewer than 50 confirmed cases globally.
- Transfusion Compatibility: Universally compatible with all Rh-negative blood types, but only compatible with Rh-null blood for transfusions.
