IgA secretions, allergies
Antigen substance that combines with an antibody
Allele alternate gene

Rh and Duffy chromosome 1
MNS chromosome 4
Kell chromosome 7
ABO chromosome 9
Kidd chromosome 18
Lewis chromosome 19
P chromosome 22
Dosage antibody reacts stronger with homozygous antigen than with heterozygous antigen
Hemolysis destruction of RBCs, indicates positive result
LISS decreases ionic strength, increasing antibody uptake rate
BSA allows antibody-sensitized cells closer together
PEG removes water molecules
Screening cells detect unexpected antibodies, type O to possess relevant antigens
IgM cold antibodies cause intravascular hemolysis
