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.

In blood grouping, the patient's serum is tested against RBCs of known blood groups and also the patient's RBCs are tested against known serum types. In this way the patient's blood group is confirmed from both RBCs and serum. A direct Coombs test is also done on the patient's blood sample in case there are any confounding antibodies.
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.
Normal red blood cells are round, flattened disks that are thinner in the middle than at the edges. A poikilocyte is an abnormally-shaped red blood cell. [1] Generally, poikilocytosis can refer to an increase in abnormal red blood cells of any shape, where they make up 10% or more of the total population of red blood cells.
This leads to a markedly decreased red blood cell count and hematocrit and markedly elevated mean cell volume and mean cell hemoglobin concentration. [ 5 ] : 32–3 Red cell agglutination also interferes with routine methods for blood typing and blood compatibility testing , which rely on agglutination reactions.
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.
