what causes really high white blood cell count?

The main causes of elevated white blood cells include: To fight a viral, fungal, bacterial, or parasitic infection. A negative reaction to a drug that triggers an immune and white blood cell response. Disease or malfunction that causes the bone marrow to overproduce white blood cells.

White blood cells help the body fight infections. Thus, if white blood cell levels are high, it can very well be an indication of an infection. “A bacterial infection is the most common kind that we see with high white blood cells,” says Dr.

White blood cell count is increased in pregnancy with the lower limit of the reference range being typically 6,000/cumm. Leucocytosis, occurring during pregnancy is due to the physiologic stress induced by the pregnant state [8].

When your body produces too many white blood cells it results in a blood disorder called leukocytosis.

More serious conditions that may cause high white blood cell counts include blood disorders, including: Leukemia. Lymphoma. Bone marrow disorders such as polycythemia vera or myelofibrosis.

Neutrophils, which account for about 70% of white blood cells, can increase in response to bacterial infections as well as to physical or emotional stress. A high lymphocyte count may occur when there is a viral or bacterial infection.

Bacteria or yeast may be observed on peripheral blood smears and may lead to spuriously elevated platelet counts. They have been reported to disturb the white blood cell (WBC) differential count if they clumped together, and a large number of such microorganisms have been shown to increase WBC counts.

Certain respiratory illnesses, such as a whooping cough or tuberculosis, may cause the levels of white blood cells to increase. In some cases, all white blood cells are affected. However, some people have a specific disease in which only one type of white blood cell is affected.

It can be caused by infections, severe allergies, or an overactive thyroid gland. An abnormally high basophil level is called basophilia. It can be a sign of chronic inflammation in your body. Or it can mean that a condition is causing too many white blood cells to be produced in your bone marrow.

High white blood cell count (leukocytosis) means having too many leukocytes circulating in the blood, usually from having an infection.

A white blood cell count that's super-high often indicates leukemia — cancer of the bone marrow. The bone marrow produces all blood cells, not just white ones but also red ones and platelets. But the malignancy causes the marrow to produce too many of the white variety.

Though it varies between individuals, a high white blood cell count (leukocytosis) is usually considered to be anything above 11,000 cells per μl of blood in an adult. This can be related to: Infection.

The exact threshold for a high white blood cell count varies from one laboratory to another. In general, for adults a count of more than 11,000 white blood cells (leukocytes) in a microliter of blood is considered a high white blood cell count.

Some conditions that can cause an increase in the monocytes in your blood are: viral infections, such as infectious mononucleosis, mumps, and measles. parasitic infections. chronic inflammatory disease.

When you get sick, your white blood cell count is higher than normal. This is because your body is releasing more of these cells to fight the infection.

Too much of a good thing? Even with all of their disease-fighting power, having too many white blood cells can actually be a bad thing. For example, a person suffering from Leukemia, a cancer of the blood, may have as many as 50,000 white blood cells in a single drop of blood.

White blood cells are vital components of the blood. Their role is to fight infection, and they are essential for health and well-being. A high white blood cell count may indicate that the immune system is working to destroy an infection. It may also be a sign of physical or emotional stress.
