When an alloantibody specificity is suspected or defined in either a donor or a patient's blood sample, the red cells should be tested with an appropriate antiserum to confirm lack of the corresponding antigen. Specific antigen negative blood may be required for crossmatching prior to transfusion to a recipient with a known alloantibody. Typing of paternal or fetal/neonatal antigens on red cells can also be an important procedure in assessing and monitoring risk in an allo-immunised pregnancy. Bio-Rad ID-Test sera for use by indirect antiglobulin test (IAT) with the ID-Card LISS/Coombs are human sera containing incomplete antibodies.
