Cell Description:
Fragmented red blood cells with varying shapes and sizes. Cells often appear small, with multiple pointed and angular ends and lack an area of central pallor.1,2
Cell Formation:
Formed in circulation when a red blood cell is damaged by mechanical means (e.g. damaged by fibrin strands or mechanical heart valves). The presence of schistocytes suggests an intravascular hemolytic process is occurring2,3
Associated Disease/Clinical States:1,2,4,5
Microangiopathic Hemolytic Anemia (MAHAs)
Macroangiopathic Hemolytic Anemias
Renal graft rejection
Severe burns
