Lewis antibodies (anti-Lea and anti-Leb) are usually naturally occurring IgM antibodies that react best at room temperature or below. They are rarely clinically significant as they do not cause Hemolytic Disease of the Newborn (HDN) and typically do not cause acute hemolytic transfusion reactions. However, they can sometimes cause a delayed serologic transfusion reaction (not clinical) and can interfere with compatibility testing.
