  7. RH Factor • Many people also have an Rh factor on the RBC’s surface. This is also an antigen. • If Rh antigen is present, you are typed Rh+ • A person with Rh- blood, does not have Rh antibodies in their blood plasma. BUT, a person with Rh- blood can DEVELOP Rh antibodies if he/she receives blood from an Rh+ person. • A person with Rh+ has no problem receiving blood from an Rh- person SBI3U | A. Manaktola

  8. Agglutination • The A antigen and the A antibodies can bind to each other in the same way that the B antigens can bind to the B antibodies. • This is what would happen if, for instance, a B blood person receives blood from an A blood person. SBI3U | A. Manaktola
