Anisopoikilocytosis is a medical condition illustrated by a variance in size (anisocytosis) and shape (poikilocytosis) of a red blood cell. The underlying cause can be attributed to various anemias, most often; beta thalassemia major, a form of microcytic anemia.
What are the causes of Anisopoikilocytosis?
Causes of anisopoikilocytosis. There’s some overlap between conditions that cause anisocytosis and poikilocytosis. This means anisopoikilocytosis can occur in the following conditions: anemias. hereditary spherocytosis. thalassemia. folate and vitamin B-12 deficiency.
What are the treatment options for Anisopoikilocytosis?
Treatment will depend on the underlying condition that’s causing anisopoikilocytosis. In some cases, treatment may involve changing your diet or taking dietary supplements. This is important when low levels of iron, folate, or vitamin B-12 cause symptoms. More severe anemia and hereditary spherocytosis may require blood transfusions to treat.
How is Anisopoikilocytosis diagnosed?
Your doctor can diagnose anisopoikilocytosis using a peripheral blood smear. For this test, a small drop of your blood is placed on a glass microscope slide and treated with a stain. The shape and size of the blood cells present on the slide can then be analyzed. A peripheral blood smear is often performed along with a complete blood count (CBC).
What is anisocytosis?
Anisocytosis is the medical term for having red blood cells (RBCs) that are unequal in size. Normally, a person’s RBCs should all be roughly the same size.
What is the cause of anisopoikilocytosis?
The most common causes of anisopoikilocytosis are blood disorders, like thalassemia and types of anemia, as well as other chronic disorders and nutritional deficiencies.
Is anisocytosis serious?
For this reason, the presence of anisocytosis is often helpful in diagnosing blood disorders like anemia. Treatment for anisocytosis depends on the cause. The condition isn't dangerous on its own, but it does indicate an underlying problem with the RBCs.
What are the symptoms of poikilocytosis?
They often include signs that the body's tissues are not getting enough oxygen delivered by the red blood cells, such as: Chronic fatigue. Weakness. Pale complexion.
What is a normal anisocytosis level?
Anisocytosis is reported as “slight” to 4+ (“four plus”) and gives the same information as the RDW parameter (red blood cell distribution width): the larger the size variation in the red blood cells, the higher the anisocytosis and RDW results will be.

Anisocytosis is Associated With Short-Term Mortality in COVID-19 and May Reflect Proinflammatory Signature in Uninfected Ambulatory Adults.
What does it mean when anisocytosis is present?
Sometimes it can lead to a diagnosis of anisocytosis. This means that your red blood cells (RBCs) are of mixed sizes. Normally, red blood cells should be about the same size. Any abnormality of your red blood cells is significant because of the important role they play in your body.
Is it normal to have poikilocytosis?
RBCs carry oxygen and nutrients to your body's tissues and organs. 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.
Can poikilocytosis be normal?
Poikilocytes typically develop due to an underlying medical condition that alters their shape. Examples include certain types of anemia, liver disease, kidney disease, and cancer. Poikilocytosis itself is not a fatal condition, but it indicates an underlying medical condition.
What are the problems caused by the abnormal shape of red blood cells?
In sickle cell anemia, some red blood cells look like sickles used to cut wheat. These unusually shaped cells give the disease its name. Sickle cell anemia is one of a group of inherited disorders known as sickle cell disease. It affects the shape of red blood cells, which carry oxygen to all parts of the body.
What is anisopoikilocytosis?
Anisopoikilocytosis refers to a condition characterized by blood with varying shapes and sizes of red blood cells (RBCs).

What type of anemia causes anisopoikilocytosis?
Types of anemia that can cause anisopoikilocytosis include iron deficiency, hemolytic, megaloblastic, and sickle cell anemias. Iron deficiency anemia, caused by a lack of iron, is characterized by the presence of RBCs that may be elongated and oval shaped (i.e., elliptocytes), as well as dacrocytes and target cells.
What is the name of the disease that causes a high concentration of hemoglobin in the center of the cell?
Thalassemia generally results in severe anisopoikilocytosis, with RBCs that resemble teardrops (i.e., dacrocytes) and have a concentration of hemoglobin in their center and periphery (i.e., target cells, also known as codocytes). Types of anemia that can cause anisopoikilocytosis include iron deficiency, hemolytic, megaloblastic, ...
What causes a sickle cell to be a first quarter moon?
Lastly, sickle cell anemia is an inherited condition affecting the formation of hemoglobin. This causes most of the RBCs to lose their flexibility and take the shape of a first-quarter, sickle moon. Aside from anemias, several chronic disorders can result in anisopoikilocytosis.
What are the symptoms of anemia?
In cases of anemia, the most common symptoms are weakness, shortness of breath, dizziness, and headaches. Additional signs that may present with anemia include an increased heart rate (i.e., tachycardia), low blood pressure (i.e., hypotension ), as well as cold and pale-colored skin.

These irregular flows can consequently affect the shape and size of RBCs. Anisopoikilocytosis can also be a complication of chronic liver or kidney disease.
Can alcohol cause anisopoikilocytosis?
Additionally, nutritional deficiencies that are associated with malnutrition, like folate and B12 deficiencies, may lead to anisopoikilocytosis. Chronic alcoholism can also affect the formation of blood cells and result in anisopoikilocytosis.
What does anisocytosis present mean?
Similarly, what does Anisocytosis present mean? Anisocytosis is a medical term meaning that a patient's red blood cells are of unequal size. This is commonly found in anemia and other blood conditions. False diagnostic flagging may be triggered by an elevated WBC count, agglutinated RBCs, RBC fragments, giant platelets or platelet clumps.

For example, anisocytosis caused by an anemia related to a diet low in vitamin B-12, folate, or iron will likely be treated by taking supplements and increasing the amount of these vitamins in your diet.
What is the name of the disorder where the immune system mistakenly destroys RBCs?
Autoimmune hemolytic anemias: This group of disorders occur when the immune system mistakenly destroys RBCs. Megaloblastic anemia: When there are fewer than normal RBCs and the RBCs are larger than normal (macrocytic anisocytosis), this anemia results. It’s typically caused by a deficiency in folate or vitamin B-12.

Sickle cell anemia: This genetic disease results in RBCs with an abnormal crescent shape. Thalassemia: This is an inherited blood disorder in which the body makes abnormal hemoglobin. It usually results in microcytic anisocytosis.
Why do pregnant women get anisocytosis?
Anisocytosis during pregnancy is most commonly caused by iron deficiency anemia. Pregnant women are at a higher risk of this because they need more iron to make RBCs for their growing baby.
What is hemolytic anemia?
Hemolytic anemia due to erythrocyte adenosine deaminase overproduction is a rare, genetic, hematologic disease characterized by mild, chronic hemolytic anemia (due to highly elevated adenosine deaminase activity in red blood cells resulting in their premature destruction), elevated reticulocyte count, splenomegaly and mild hyperbilirubinemia. Other cells and tissues are not affected.

What is the difference between microcytosis and anisocytosis?
Normocytic anemia: This is a blood problem when a person has normal-sized red blood cells, but there is a low amount of them. Microcytosis: This is when the red blood cells are smaller than usual. Anisocytosis is when there is an increased variation in these cell sizes.
What is anisocytosis in anemia?
Anisocytosis is prominent in iron deficiency anemia and is a condition where the red blood cells are unequal in size. Image credit: Dr Graham Beards, 2012. Anemia can be broken down into three different types: macrocytic, normocytic, and microcytic: Macrocytosis: This refers to when red blood cells are larger than usual.
