Test of Antigen S
The antigens S (MNS3) and s (MNS4) are carried on the human glycophrin B (GPB) molecule and are part of the MNS system. Ss antibodies are not frequently encountered, however they have both been implicated in rare cases of severe hemolytic disease of the newborn and rare cases of mild to moderate hemolytic transfusion reactions, and are therefore clinically important. Antigen typing of paternal or fetal/neonatal or donor bloods may also therefore be appropriate, according to the clinical situation.
