Explanation

Blood groups: A (has A antigens), B (has B antigens), AB (has both), O (has neither). Rhesus factor: positive (has Rh antigen) or negative (lacks it). Eight combinations: A+, A-, B+, B-, AB+, AB-, O+, O-.

Transfusion compatibility: cannot receive blood with antigens you lack (body attacks foreign antigens). O- is universal donor; AB+ is universal recipient. Mismatch causes serious reaction.

Blood typing before transfusion is essential. Rh incompatibility in pregnancy (Rh- mother, Rh+ baby) can cause problems in subsequent pregnancies without treatment.
