None, every group is the “best” one for the patient who needs it. There is no superior blood type, only different supply maths. ## The honest answer O− is the most useful in emergencies (universal red cells), AB+ patients can receive from everyone, and AB plasma is universal. Each group’s advantage is somebody else’s shortage. The group India needs most is simply the one running short at your nearest bank this week, check e-RaktKosh and you will see it move. ## If this is your moment Blood cannot wait for curiosity to settle, patients wait in hours, not weeks. If you are healthy and between 18 and 65, register as a donor (two minutes, phone OTP) and let the system call you only when someone near you actually needs your group.
