Notes:

Thermal amplitude is the temperature range over which an antibody can react.  Cold reactive autoantibodies occasionally exhibit thermal amplitude 20-24° Celsius or higher) and may interfere with routine cell and serum tests.  Physicians may request a thermal amplitude test before performing certain surgical procedures when these antibodies are identified.
