Causes of a High Absolute Monocyte Count. A high absolute monocyte count, or monocytosis, can be the result of a viral infection such as mononucleosis, mumps or measles. In some cases, a more serious disease may be indicated by a high monocyte count such as tuberculosis, pneumonia, leukemia or chronic inflammatory disease.


Helpful, trusted answers from doctors: Dr. Miller on elevated monocytes in children: High white blood cell counts are most typically seen in infectious diseases, but may also be the cardinal sign of leukemia. Ask your doctor if you have this.


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 ...


Find out what it means if monocyte levels are high or low in blood test results, including symptoms of abnormal absolute mono levels and causes of elevated or decreased monocytes in blood test. Also learn how to calculate absolute monocyte count and it differs from relative monocyte count.


Low or high numbers of monocytes do not usually cause symptoms. However, people may have symptoms of the disorder that caused the change in monocyte number. Diagnosis is by blood testing (complete blood count) done when a person has signs or symptoms of an infection or autoimmune disorder.


A high monocyte count can indicate the presence of a blood disorder, an autoimmune disease or a chronic infection. High monocyte levels are also linked to certain types of cancer. Monocytes are a type of white blood cell. One of their main roles is to help the body fight off infection.


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). After a few hours they migrate to tissues such as the spleen, liver, lung, and bone marrow, where they mature into macrophages, the main scavenger cells of the immune system.


Clinically high monocytes count is termed as monocytosis. Monocytosis is aggravated with increased stress level. Other abnormality in physiological condition includes inflammation, viral infection (measles and mumps), severe bacterial infection (pneumonia), parasitic infection, increased cell fatality, malfunction in immune system, and resurrection of RBCs (Red Blood Cells).


Differential; White blood cell differential count. How the Test is Performed. The health care provider will take blood from your vein. The blood collects into an airtight container. In infants or a young child, blood will be taken from a heel stick or finger stick. The blood is collected in a small glass tube or onto a slide or test strip.


If your child has too few or too many white blood cells, in general, here's what it means: Low white blood cell count (leukopenia) means having too few leukocytes circulating in the blood. A long-term low white blood cell count increases the risk of infections and may be caused by a number of different diseases and conditions.
