group ‘B’ blood type
has only the B antigen on red cells and A antibody in plasma
group ‘AB’ blood type
has A and B antigens on red cells( but neither a nor b antibody in plasma)
group O blood type
has neither A nor B on red cells (but both A and B antibody in plasma
how to determine a persons blood type
blood samples are mixed with A and B antibodies to see if the blood cells stick together
