<prompt> Antibody associated with cold antibody immunohemolytic anemia is:IgAIgEIgGIgM  <response>: Cold antibody immunohemolytic anemia usually is caused by low-affinity IgM antibodies that bind to red cell membranes only at temperatures below 30C, occurs in distal parts of the body e.g., ears, hands, and toes in cold weather. Warm antibody immunohemolytic anemia is caused by immunoglobulin G IgG or rarely IgA antibodies that are active at 37C.
