The Rarest of the Rare: Bombay Blood Group (hh)

Discovered in Mumbai (then Bombay) in 1952 by Dr. Y.M. Bhende, the **Bombay Blood Group (hh)** is a genetic rarity that affects only 1 in 10,000 Indians (and 1 in a million globally).

What Makes It Special?

Most people have the 'H' antigen, which helps make A, B, or O blood types. Bombay phenotype individuals **lack this H antigen entirely**.
The Consequence: They can donate to anyone (ABO groups), but they can ONLY receive blood from another Bombay Blood Group person. Regular O- blood will kill them.

Why Registry Matters

Finding an 'hh' donor in an emergency is like finding a needle in a haystack. JeevanSeva maintains a specialized **Rare Blood Donor Registry**. We track:

• Bombay Blood Group (hh)
• AB Negative (AB-)
• Rh Null ("Golden Blood")

If you have a rare blood type, registering with us is not just charity—it's an insurance policy for your own life.
