When<unk> -negative individuals are exposed to<unk> -positive blood through transfusion or pregnancy, they may develop an anti-Lan antibody. Anti-Lan is considered a clinically significant antibody, but its effects are variable. It has been associated with severe transfusion reactions and mild cases of hemolytic disease of the newborn, but in some cases individuals with the antibody have not experienced any adverse effects from exposure to<unk> -positive blood. It is recommended that individuals with anti-Lan are transfused with<unk> -negative blood, especially if the antibody titer is high. One case of autoimmune hemolytic anemia involving auto-anti-Lan has been described.
