Echinocytosis is a reversible condition of red blood cells that is often merely an artifact produced by EDTA, which is used as an anticoagulant in sampled blood. [3] Echinocytes can be distinguished from acanthocytes by the shape of the projections, which are smaller and more numerous than in acanthocytes and are evenly spaced.
Acanthocytes should be distinguished from echinocytes, which are also called 'burr cells', which although crenated are dissimilar in that they have multiple, small, projecting spiculations at regular intervals on the cell membrane. [7] [12] Burr cells usually imply uremia, but are seen in many conditions, including mild hemolysis in ...

The formation of the fibrin strands in the vessels occurs as part of the clot formation process. The red blood cells get trapped in the fibrin strands and the shear force of the blood flow causes the red blood cell to break. The resulting fragmented cell is called the schistocyte. [4]
Rouleaux (singular is rouleau) are stacks or aggregations of red blood cells (RBCs) that form because of the unique discoid shape of the cells in vertebrates. The flat surface of the discoid RBCs gives them a large surface area to make contact with and stick to each other; thus forming a rouleau.
These cells still contain a nucleus as well due to the early release, which is not needed in mature blood cells because their only function is to carry oxygen in the blood. The life span of a typical red blood cell is acknowledged to be approximately 120 days, and the time period of a reticulocyte found in the blood to be one day.

Microangiopathic hemolytic anemia may be suspected based on routine medical laboratory tests such as a CBC (complete blood cell count). Automated analysers (the machines that perform routine full blood counts in most hospitals) are designed to flag blood specimens that contain abnormal amounts of red blood cell fragments or schistocytes.
