Does normal blood contain cold agglutinin?
Test overview
Cold agglutinin levels are generally lower in healthy people in their blood. But lymphoma or certain infections, such as Mycoplasma pneumoniae, can cause elevated cold agglutinin levels. Higher-than-normal levels of cold agglutinin usually do not cause serious problems.
What is cold agglutinin in blood?
Cold agglutinins – cold agglutinins are Antibodies that recognize red blood cell (RBC) antigens at temperatures below normal core body temperature. They can cause red blood cell agglutination (picture 1) and extravascular hemolysis, resulting in anemia, usually without hemoglobinuria.
How is cold agglutinin diagnosed?
In some cases, the diagnosis is first incidental, if Routine complete blood count (CBC) Detects abnormal aggregation (agglutination) of red blood cells. In most cases, the diagnosis is based on evidence of hemolytic anemia (from symptoms and/or blood tests).
What is cold agglutinin?
The cold agglutinin titer is Diagnostic tests for cold agglutinin disease (CAD). High levels of cold agglutinins, mainly autoantibodies of the IgM type, can bind and induce agglutination (or clumping) and destruction of red blood cells (RBCs) when exposed to low temperatures.
