What was discovered

A rare blood type (hh) in which red cells lack the H antigen that precedes A and B, so these people can only receive blood from other hh donors. First described in Bombay, it is more common on the Indian subcontinent.

What it led to

  • Blood-bank protocols for rare blood types
  • A finer understanding of ABO blood-group genetics
