Typical schistocytes are annotated. A schistocyte or schizocyte (from Greek schistos for "divided" and kytos for "hollow" or "cell") is a fragmented part of a red blood cell . Schistocytes are typically irregularly shaped, jagged, and have two pointed ends.

Schistocytes are usually seen in relatively low numbers and are associated with conditions in which the normally smooth endothelial lining, or endothelium, is roughened or irregular, and/or the vascular lumen is crossed by strands of fibrin. [18] Schistocytes are commonly seen in patients that have hemolytic anemia.

Acanthocyte (from the Greek word ἄκανθα acantha, meaning 'thorn'), in biology and medicine, refers to an abnormal form of red blood cell that has a spiked cell membrane, due to thorny projections. [1] [2] A similar term is spur cells. Often they may be confused with echinocytes or schistocytes.
The presence of schistocytes is a key finding that helps to diagnose HUS. Shiga-toxin directly activates the alternative complement pathway and also interferes with complement regulation by binding to complement factor H, an inhibitor of the complement cascade.

As HIIHA progresses reticulocytes increase leading to an elevated mean corpuscular volume. Indirect bilirubin and Lactate dehydrogenase become elevated. LFTs occasionally become elevated. In some cases, a peripheral blood smear may show schistocytes, anisocytosis, polychromasia, or poikilocytosis. [7]
