COLD HEMAGGLUTININS 0000349

Cold Hemagglutinins (or cold agglutinins) can be useful in helping to determine the cause of hemolytic anemia and help diagnose cold agglutinin syndrome. When you have symptoms associated with anemia and/or pain, paleness, and bluing in the fingers, toes and tips of the ears that occurs after exposure to cold temperatures, your doctor may test for this disease.
