Find B Negative Blood Donors Near You
Common letter, rare sign: ~1–2% of the population.
A deceptive difficulty
Families assume 'B is common' and start late — but B− specifically is one of India's scarcer groups, and stock is thin outside big-city banks.
Sources for a B− patient
B− or O− only. Post early, flag the negative group prominently in shares, and ask the blood bank about exchange arrangements with other banks.
B− donors: you're on call
Few enough that each registration changes local coverage; recruit siblings — the phenotype clusters in families.
Frequently asked questions
How urgent should a planned B− surgery request be?
Raise it days ahead as 'planned' — negative groups reward preparation more than urgency flags.
Whom do B− donors serve?
B−, B+, AB− and AB+ patients — a four-group reach that makes B− donations especially efficient.
