What is considered a high monocyte count?

At a Glance Typically, this represents a monocyte count greater than 800 per microliter in adults. Monocyte counts may be significantly higher in children (e.g., up to 3000 per microliter), and age -specific normals should be used to determine if the monocyte count is truly elevated in a younger patient.

Should I worry about high monocytes?

Monocytes and other kinds of white blood cells are necessary to help the body fight disease and infection. Low levels can result from certain medical treatments or bone marrow problems, while high levels can indicate the presence of chronic infections or an autoimmune disease.

Can stress cause high monocytes?

An increase in monocytes may be due to an infection by bacteria, fungus, or virus. It can also be a response to stress. Elevated monocyte counts may be due to a problem with blood cell production. In certain cases, the excess is due to a malignancy, such as certain types of leukemia.

What is a normal range for monocytes?

The normal absolute monocytes range is between 1 and 10% of the body’s white blood cells. If the body has 8000 white blood cells, then the normal absolute monocytes range is between 80 and 800.

What does a monocyte do?

Monocytes are bone marrow derived leukocytes that circulate in the blood and spleen. They are characterized by their ability to recognize “danger signals” via pattern recognition receptors. Monocytes can phagocytose and present antigens, secrete chemokines, and proliferate in response to infection and injury.

What does Monocytosis indicate?

Monocytosis is defined as a monocyte count that exceeds the upper limit of the reference range of 0.95 X 199/L (950/μL). Monocytosis is commonly caused by the following conditions: Bacterial infections: These include tuberculosis, subacute bacterial endocarditis, and brucellosis.

What is mono% in blood test?

The mononucleosis test is used to help determine whether a person with symptoms has infectious mononucleosis ( mono ). The test is used to detect proteins in the blood called heterophile antibodies that are produced by the immune system in response to an Epstein-Barr virus (EBV) infection, the most common cause of mono.

What happen if white blood cells are high?

A high white blood cell count usually indicates: An increased production of white blood cells to fight an infection. A reaction to a drug that increases white blood cell production. A disease of bone marrow, causing abnormally high production of white blood cells.

How does stress affect the endocrine system?

During times of stress, the hypothalamus, a collection of nuclei that connects the brain and the endocrine system, signals the pituitary gland to produce a hormone, which in turn signals the adrenal glands, located above the kidneys, to increase the production of cortisol.
