Find AB Negative Blood Donors Near You
India's rarest major group — well under 1%.
The 1-in-200 group
AB− is the least common of the eight majors in India; many banks stock zero units and rely entirely on calling known donors when a case arrives.
Sources for an AB− patient
AB−, A−, B− or O− — all negatives, all scarce. Requests should go wide immediately and lean on rare-donor registries alongside HelpALife alerts.
AB− donors: register today
You may wait years between calls, but when the call comes there is often literally no one else within a hundred kilometres.
Frequently asked questions
Should AB− patients bank their own blood?
Before planned surgery, autologous pre-donation is worth asking about — the bank will advise.
What plasma role do AB− donors have?
AB plasma is universal — AB− donors are precious on both sides of the ledger.
