Why can type O blood be donated to anyone?
It contains neither A antigen nor B antigen. their blood can be given to individuals of any other blood group red cells do not carry either A or B antigen and hence they do not react with their corresponding antibodies. Remember that an immune respond can only be trigger when the antigen is present in the blood. In another word the blood originally have no any antibody but upon antigen contact it will trigger the immune respond thus antibody is produced and agglutination of blood occur. for rhesus factor there are memory cell so the antibody is still present. That is why when an O blood group without any antigen and antibody (it have both antibody but it is not create yet as there is nothing to trigger its immune respond) can donate to AB group which has no antibody (which mean it will not be trigger by any blood group) but have both antigen (remember that all donated blood have no antibody as there is no immune respond to trigger it thus the AB blood with both antigen is fine; except rhesus factor if it have memory cell)
Blood test to identify antigen-antibody reactions?
