What antibodies are part of the Duffy blood group?

The Duffy blood group system consists of antigens that are classified as Fya and Fyb. Individuals may produce antibodies against these antigens when exposed to incompatible blood. Specifically, anti-Fya and anti-Fyb are the antibodies associated with the Duffy blood group, which can be clinically significant during blood transfusions or pregnancies.

The Duffy antigens are particularly relevant in certain populations, especially in relation to malaria susceptibility, as the absence of these antigens can confer some level of protection against the disease. Understanding the role of the Duffy blood group in transfusion medicine is essential for medical laboratory scientists.

Other options mention different blood group systems or antibodies. For example, anti-Chido and anti-Rogers pertain to the Chido/Rodgers blood group system; Jka and Jkb are associated with the Kidd blood group system; and anti-S and anti-s belong to the MNS blood group system. Each of these involves different antigens and antibodies with their unique clinical implications, but they do not pertain to the Duffy blood group.
