What Causes a High Monocyte Count? Monocytes are white blood cells that are common to the blood of all vertebrates and they help the immune system to function properly. There are a number of reasons for a high monocyte count, which can also be called monocytosis. Some of the reasons can include stress, viral fevers, inflammation and organ necrosis.

Intelligence: Knowns and Unknowns A high platelet count (thrombocytosis) can happen for many reasons. Infections are often accompanied by a high platelet count. That is more common in children than adults.

Polycythemia (Elevated Red Blood Cell Count) 1 Polycythemia means increased red blood cell volume. 2  Polycythemia is divided into two main categories; primary and secondary.  Polycythemia can be linked to secondary causes, such as, chronic hypoxia or tumors releasing erythropoietin.

- Some of the most common causes of a low monocyte count are illnesses that affect the bone marrow, such as HIV, rheumatoid arthritis, or lupus. A low monocyte count may be caused by a vitamin deficiency. Illnesses that affect bone marrow like rheumatoid arthritis may be the cause of a low monocyte count.

Reticulocytes 1 Hemolytic anemia: In this condition, anemia is caused by increased destruction of RBCs. The bone marrow increases RBC production to compensate, resulting in a high reticulocyte count.  Hemolytic disease of the newborn: This condition causes increased RBC destruction, similar to hemolytic anemia described above.

Macrocytic anemia In a macrocytic anemia, the larger red cells are always associated with insufficient numbers of cells and often also insufficient hemoglobin content per cell. Both of these factors work to the opposite effect of larger cell size, to finally result in a total blood hemoglobin concentration that is less than normal (i.e., anemia).

Learn how UpToDate can help you. Macrocytosis is a descriptive term for red blood cell (RBC) size larger than the normal range. It may be caused by abnormalities of RBC production in the bone marrow, altered RBC membrane composition, or an increase in the percentage of reticulocytes, which are larger than mature RBCs. This topic discusses causes of macrocytosis and macrocytic anemia. Additional topics discuss the following:

Common Causes Of High Hemoglobin Levels (Polycythemia) Here’s a look at the causes of high hemoglobin and hematocrit levels. 1. Genetic Mutation: Polycythemia Vera. For some people, the high hemoglobin and hematocrit levels are due to a genetic mutation. This kind of increased level of red blood cells is known as primary polycythemia or polycythemia vera.

- Inflammation: A number of different types of inflammation, with or without infection can cause increase in monocyte count. It is not, by itself, diagnostic of any disease. It would be prudent to discuss it with the doctor who ordered the test as s/he has more information about your health. ...Read more.

- Excessive numbers of white blood cells are most often due to the response of normal bone marrow to infection or inflammation. In some instances, leukocytosis is a sign of more serious primary bone marrow disease (leukemias or myeloproliferative disorders).

- A: A low number of monocytes in the blood usually indicates an increased risk for infections. A low monocyte blood count may occur because of a range of diseases that affect the bone marrow, such as rheumatoid arthritis, HIV or lupus. Monocytes are produced by the bone marrow and are a type of white blood cell.

- The most common cause of macrocytic anemia is megaloblastic anemia, which is the result of impaired DNA synthesis. Although DNA synthesis is impaired, RNA synthesis is unaffected, leading to a buildup of cytoplasmic components in a slowly dividing cell. This results in a larger-than-normal cell.

Polycythemia (Elevated Red Blood Cell Count) A. Polycythemia is a condition that results in an increased level of circulating red blood cells in the bloodstream. People with polycythemia have an increase in hematocrit, hemoglobin, or red blood cell count above the normal limits. Polycythemia is normally reported in terms of increased hematocrit or hemoglobin. Primary polycythemia: In primary polycythemia the increase in red blood cells is due to inherent problems in the process of red blood cell production. 2  Secondary polycythemia: Secondary polycythemia generally occurs as a response to other factors or underlying conditions that promote red blood cell production.

- CMML patients have a high number of monocytes in their blood (at least 1,000 per mm 3). Often, the monocyte count is much higher, causing their total white blood cell count to become very high as well.Usually there are abnormal cells in the bone marrow, but the amount of blasts (very early/immature cells) is below 20%.Many patients have enlarged spleens (an organ that lies just below the left rib cage).he 2 major types of white blood cells are lymphocytes and granulocytes. Lymphocytes are immune cells in the bone marrow, the blood, and in lymph nodes. Some kinds of lymphocytes make the antibodies that help your body fight germs.

- A low number of monocytes in the blood usually indicates an increased risk for infections. A low monocyte blood count may occur because of a range of diseases that affect the bone marrow, such as rheumatoid arthritis, HIV or lupus. Monocytes are produced by the bone marrow and are a type of white blood cell. They account for up to 10 percent of the circulating white blood cells in the human body. Their main role is to destroy cancer cells and infectious organisms that invade the body.

What does high absolute monocytes mean on your blool results? Report Abuse. A high level of monocytes could mean a number of things. They're a type of phagocyte-a type of cell found in your blood that 'eats' many types of attacking bacteria and other microorganisms when it matures. High levels could mean that you have an infection as more develop to fight it.

What Are normal Monocyte Values Normal moncoyte values. Monocytes account for between 4 and 8% of white blood cells. In a blood test their value can be found in the section on Complete Blood Count with the other types of white blood cells. Normal monocyte values are between 1000 and 4500 cells per ml. Therefore, if your monocyte count is between these two values, you can rest assured that it is a normal count and everything is fine. High monocyte values When monocytes exceed normal values it is almost always due to infections caused by viruses or parasites, such as the following: However, a high monocyte count can also be caused by a chronic inflammatory disease, tuberculosis, tumours or leukaemia. A high monocyte count is called monocytosis.

- Large platelets may be seen in any disorderassociated with increased platelet turnover, such as may occur with idiopathicthrombocytopenic purpura or bleedingdisorders. In addition to the elevated platelet count, morphological changes may also occur postsplenectomy.

Evaluation of Microcytosis Microcytosis is typically an incidental finding in asymptomatic patients who received a complete blood count for other reasons. The condition is defined as a mean corpuscular volume of less than 80 μm3 (80 fL) in adults. The most common causes of microcytosis are iron deficiency anemia and thalassemia trait. Other diagnoses to consider include anemia of chronic disease, lead toxicity, and sideroblastic anemia.

Monocyte Disorders Monocytes are produced in the bone marrow and then enter the bloodstream, where they account for about 1 to 10% of the circulating leukocytes (200 to 600 monocytes per microliter of blood).

Monocytosis Monocytosis is a rare blood disorder of cats characterised as an absolute number of circulating monocytes greater than the reference range of 0.9 x 109/l or 900/µl or mm3. In cats, monocytes are derived from hematopoietic stem cells named the colony-forming unit granulocyte, monocyte (CFU-GM).

What Causes a High Monocyte Count? A physician may order a monocyte blood count test to check for raised levels of monocytes. There are a number of reasons for this test, from a simple health check up to people suffering from heart attacks and leukemia. Complications with the blood and cancer are two other reasons that this test may be performed.hysical injuries may cause organ necrosis, which may result in a high monocyte count. Blood may be drawn to test monocyte levels. Viral fevers can cause a high monocyte count.
