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.
Crenation (from modern Latin crenatus meaning "scalloped or notched", from popular Latin crena meaning "notch") [1] in botany and zoology, describes an object's shape, especially a leaf or shell, as being round-toothed or having a scalloped edge.

Red blood cell indices are blood tests that provide information about the hemoglobin content and size of red blood cells. Abnormal values indicate the presence of anemia and which type of anemia it is.
All values in Hematology – red blood cells (except hemoglobin in plasma) All values in Hematology – white blood cells; Platelet count (Plt) A few values are for inside red blood cells only: Vitamin B 9 (folic acid/folate) in red blood cells; Mean corpuscular hemoglobin concentration (MCHC)
Red blood cell distribution width (RDW), as well as various types thereof (RDW-CV or RCDW and RDW-SD), is a measure of the range of variation of red blood cell (RBC) volume that is reported as part of a standard complete blood count. [1] Red blood cells have an average volume of 80–100 femtoliters, but individual cell volumes vary even in ...
This occurs when there is damage to the blood vessel and a clot begins to form. 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 ...
Beta-hemolysis (β-hemolysis), sometimes called complete hemolysis, is a complete lysis of red cells in the media around and under the colonies: the area appears lightened (yellow) and transparent. [1] Streptolysin, an exotoxin, is the enzyme produced by the bacteria which causes the complete lysis of red blood cells. There are two types of ...
