LOINC description : Used to identify blood group A IgG antibodies in newborns that have a positive direct
antiglobulin test (DAT). Hemolytic disease of the newborn (HDN) caused by ABO antibodies
occurs almost exclusively in infants of blood group A or B who are born to group O
mothers because the anti-A and anti-B formed in group O individuals tend to be of
the IgG type. [PMID: 8021795];
