What is anisocytosis and how is it treated?
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 other disorders can cause anisocytosis?
Other disorders that can cause anisocytosis include: In addition, certain drugs used to treat cancer, known as cytotoxic chemotherapy drugs, can result in anisocytosis. Anisocytosis may also be seen in those with cardiovascular disease and some cancers.
How do you know if you have anisocytosis?
The results will determine what type of anisocytosis the person has. If the red blood cells are smaller than normal, this can be a sign of low iron or sickle cell anemia. If the red blood cells are larger than normal, the cause could be a vitamin deficiency, liver disease, or a number of other conditions.
What is the difference between cytosis and anisocytosis?
“Aniso” means unequal, and “cytosis” refers to the movement, features, or number of cells. Anisocytosis itself is a nonspecific term, as there are several different ways in which cells can be unequal.
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 does anisocytosis mean in a blood test?

What is Myelocytes blood test?
Myelocytes, along with metamyelocytes and promyelocytes, are the precursors of neutrophils, the largest class of white blood cell. These immature neutrophils are normally found only in the bone marrow. In the blood, metamyelocytes are the most often observed, accompanied by a few myelocytes.
What is the measurement of anisocytosis?
Measuring Anisocytosis. Anisocytosis is diagnosed using a measurement called red blood cell distribution width (RDW). A high RDW value means that the variation in the size of your red blood cells is higher than normal. A high RDW value can be caused by cells that are larger than normal, smaller than normal, or both.
What does a blood smear tell you about anisocytosis?
What to Know About Anisocytosis. A simple blood smear can tell your doctor a lot about your health. It allows them to observe the number, size, and shape of your blood cells. 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.
Why is megaloblastic anemia called normocytic?
It is also known as megaloblastic anemia because some of the red blood cells are large and abnormally shaped. Some kinds of anemia do not have anisocytosis as a symptom. These are called normocytic because the red blood cells are of normal size. An RDW test is still helpful here. It can rule out some types of anemia.
Why is it important to have abnormal red blood cells?
Any abnormality of your red blood cells is significant because of the important role they play in your body. Scientists are still investigating anisocytosis and its relationship with disease.

Iron deficiency is most often caused by blood loss. Insufficient iron in your diet or a problem absorbing the iron you consume can also cause it. Vitamin deficiency anemia. A shortage of vitamin B12 or folate or both can cause this anemia.
Why do red blood cells not have a nucleus?
This shape allows them to fold over so they can fit through your narrowest blood vessels. The lack of a nucleus means that red blood cells don't live long. Their life span is just 3 months.
How to treat anisocytosis?
In extreme cases of anisocytosis, a doctor may recommend a blood transfusion. This process can replace the blood containing abnormal cells with blood containing normal cells.
How to diagnose anisocytosis?
The way to diagnose anisocytosis is with a blood smear. This will be conducted by a skilled professional, often a laboratory scientist, hematologist, or pathologist. A blood sample is taken and then examined under a microscope to see if the cells are abnormal in shape or unequal in size.
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.
What is anisocytosis in medical terms?

What is aplastic anemia?
Aplastic anemia is a rare bone marrow disorder that develops when the body does not make enough blood cells. Viral infections, radiation, exposure to toxic chemicals, and drug use can cause aplastic anemia. Hemolytic anemia happens when red blood cells are broken up.
Why is iron deficiency anemia common?
It develops when there is not enough iron in the blood and is often due to blood loss. It can also be caused by poor iron absorption from childbirth, pregna ncy, and having gastric bypass surgery.

Common causes of macrocytosis include: Vitamin B-12 deficiency. Folate deficiency. Liver disease. Alcoholism. Hypothyroidism. A side effect of certain medications, such as those used to treat cancer, seizures and autoimmune disorders. Increased red blood cell production by the bone marrow to correct anemia, for example, after blood loss.
What causes increased red blood cell production in the bone marrow?
Increased red blood cell production by the bone marrow to correct anemia, for example, after blood loss. An underlying bone marrow cancer called myelodysplastic syndrome. If you have macrocytosis, blood tests can help determine its cause.
What is the term for red blood cells that are larger than normal?
Macrocytosis is a term used to describe red blood cells that are larger than normal. Also known as megalocytosis or macrocythemia, this condition typically causes no signs or symptoms and is usually detected incidentally on routine blood tests.
Abstract

What does the name Anisocytosis mean?
Anisocytosis Meaning. The name Anisocytosis has been derived from two different words, “aniso” meaning “unequal”, and “cytosis” which has a reference to cells.
Why do you need blood transfusion for anisocytosis?
Blood Transfusion. Blood transfusion can be a major reason behind Anisocytosis and much care need to be taken during the process. A test should be conducted to check whether the size of the red blood cells in the transfused blood is same as that present in his/her body at that time.
What is the condition called when the bone marrow is unable to make enough red blood cells?
Diamond-Blackfan Anemia. Diamond-Blackfan anemia is a condition in which the bone marrow is unable to make sufficient red blood cells. Anisocytosis may be one of the signs of anemia of this kind.
What does it mean when your red blood cells are high?
High values of variable-sized red blood cells indicate the presence of Anisocytosis. Once an abnormality is detected, doctors start the treatment of the condition. If the varying red blood cells are low in number, doctors categorize the condition as +1 Anisocytosis. But if the quantity is found to be greater, it is regarded as a case ...
Why is lack of iron important?
Lack of iron can reduce your red blood cells to a great extent, resulting in anemia, and ultimately leading to Anisocytosis.
Can anisocytosis cause physical discomfort?
However, the condition causes a lot of physical discomfort and can be a sign of some more complicated disorders. If you are having Anisocytosis yourself or know someone suffering from it, it is best to get medical treatment as early as possible. References. http://en.wikipedia.org/wiki/Anisocytosis.
Can you contract anisocytosis from blood transfusion?
Generally, if the new blood cells are not around the same size and shape, then it is possible to contract a temporary form of anisocytosis.
Can anisocytosis be misdiagnosed?
Because anisocytosis can indicate any of a number of other conditions, there is a probability of misdiagnosing the cause of it. ( 10) There is also a possibility of misdiagnosing anisocytosis itself.
