The complete ABO/Rh compatibility table, red cells, plasma and who can receive from whom, on one page. ## The honest answer Red cells: O− gives everyone, AB+ receives everyone. Plasma runs opposite: AB gives everyone, O receives only O. Rh matters for red cells, barely for plasma. Print this for camp desks. Remember the final check is always the crossmatch, the chart decides compatibility on paper; the lab decides it in reality. ## 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.
