This article reviews information regarding the clinical significance of antibodies to antigens in the Scianna, Dombrock, Colton, Landsteiner-Wiener, Chido/Rodgers, H, Kx, Cromer, Gerbich, Knops, Indian, and Ok blood group systems. Like most blood group systems, antibodies to many of the antigens in these groups are rarely encountered because of the high prevalence of the associated antigens in most populations. For many, the clinical significance—that is, the potential to cause reduced survival of transfused antigen-positive red blood cells or a transfusion reaction (e.g., anti-Ge2, anti-H) and/or hemolytic disease of the fetus and newborn (e.g., anti-Coa, anti-Ge3)— has been documented. Some of these antibodies are not always clinically significant, and because of the high prevalence of the antigen, antigen-negative blood may be extremely difficult to find (e.g., anti-LW, anti-Inb). The use of a monocyte monolayer assay may be helpful when making transfusion decisions for patients with these antibodies. For others, their prevalence is so rare that information on the clinical significance of their antibodies is not available (e.g., anti-Co4, anti-Ok). <italic><bold>Immunohematology</bold></italic> <bold>2018;34:103–108.</bold>
