What is the rarest blood type?
Answer
Type Bombay
Type Bombay (also called hh blood type) is the world's rarest blood type, found primarily in India and parts of the Middle East and South Asia. This blood type lacks H antigen, making it incompatible with all standard blood types. People with Bombay blood can only safely receive transfusions from other Bombay donors, creating serious medical challenges in regions where it's rare.
