Cold agglutinins, or cold autoantibodies, occur naturally in nearly all individuals. These natural cold autoantibodies occur at low titers, less than 1:64 measured at 4 °C, and have no activity at higher temperatures. Pathologic cold agglutinins occur at titers over 1:1000 and react at 28-31 °C and sometimes at 37 °C.

Symptoms of AIHA may be due to the underlying anemia; including shortness of breath or dyspnea, fatigue, headache, muscle weakness and pallor.
