Why are my RBCs irregular?
If your RBCs are irregularly shaped, they may not be able to carry enough oxygen. Poikilocytosis is usually caused by another medical condition, such as anemia, liver disease, alcoholism, or an inherited blood disorder.

What are the symptoms of poikilocytosis?
Poikilocytosis can also be considered a symptom of many other disorders. Common symptoms of other blood-related disorders, such as anemia, include: fatigue. pale skin.
How to diagnose poikilocytosis?
Poikilocytosis may be diagnosed during a test called a blood smear. This test may be done during a routine physical exam, or if you’re experiencing unexplained symptoms.
Can you see RBCs under a microscope?
The doctor then views the blood under a microscope, where the sizes and shapes of the RBCs can be seen. Not every single RBC will take on an abnormal shape. People with poikilocytosis have normally shaped cells mixed in with abnormally shaped cells.
Can you have more than one poikilocytosis?
The type depends on the characteristics of the abnormally shaped RBCs. While it’s possible to have more than one type of poikilocyte present in the blood at any given time, usually one type will outnumber the others.
Is poikilocytosis a long term condition?
The long-term outlook for poikilocytosis depends on the cause and how quickly you’re treated. Anemia caused by iron deficiency is treatable and often curable, but it can be dangerous if not treated. This is especially true if you’re pregnant .
What is abnormally shaped blood cells called?
Abnormally shaped blood cells are called poikilocytes. Normally, a person’s RBCs (also called erythrocytes) are disk-shaped with a flattened center on both sides. Poikilocytes may: be flatter than normal. be elongated, crescent-shaped, or teardrop-shaped. have pointy projections.
What are the causes of poikilocytosis?
Diagnostic Significance: Many different forms of poikilocytes exist, as well as many different causes of poikilocytosis; a few important causes include the following: •. In vitro artifactual changes (echinocytes and some acanthocytes) •. RBC fragmentation ( schistocytes and keratocytes) •. Membrane loss (spherocytes) •.
What is the term for abnormally shaped erythrocytes?
Erythrocytes can assume a wide variety of shapes. Poikilocytosis is a general term used to describe the presence of abnormally shaped erythrocytes. Although specific terminology is used for certain abnormal shapes, it is less important to quantify each type of shape change than it is to determine the cause of the shape change. 509 Poikilocytosis may be present in clinically normal goats and young cattle ( Figs. 4-5, 4-35 ). 225,409 In some instances, these shapes appear to be related to the hemoglobin types present, but an abnormality in protein 4.2 in the membrane has been suggested as a causative factor in calves. 352 Increased numbers of poikilocytes are also present in human preterm and term neonates. 403
What causes a cat to have a shortened RBC?
Anemia of chronic hepatic disease may have multiple causes (see Chapter 9). Abnormal lipid metabolism may cause altered RBC shapes (i.e., acanthocytes) and a shortened RBC life span. Marked poikilocytosis is a frequent finding in cats with hepatic lipidosis and inflammatory liver disease. Coagulation defects, caused by reduced hepatic synthesis of coagulation and anticoagulant factors, may cause hemorrhage particularly in cats. Decreased hepatic function can lead to deficiencies of nutrients needed for hematopoiesis. Microcytosis is a frequent finding in dogs with a PSS. These dogs often have a “functional iron deficiency” with increased hepatic iron but low serum iron, normal total iron-binding capacity (TIBC), and low percentage saturation of iron (Table 3-3 ). 15
