Causes. A low white blood cell count usually is caused by one of the following: 1  Viral infections that temporarily disrupt bone marrow function. 2  Congenital disorders characterized by diminished bone marrow function. 3  Cancer or other diseases that damage bone marrow. 4  Autoimmune disorders that destroy white blood cells or bone marrow cells.

1 Leukopenia-a decrease in the total number of white blood cells (WBC), which may lead to low white blood cell count. 2  Neutropenia-a decrease in the number of neutrophils, one type of white blood cell, which may lead to low white blood cell count.

A. White blood cells (WBC's) are the ones responsible for the immune system in the body. The white blood cell count rises in cases of infection, steroid use and other conditions. A low white blood cell count can have many causes, which need to be further evaluated by a doctor.

Neutrophils are the most abundant white blood cell, constituting 60-70% of the circulating leukocytes. They defend against bacterial or fungal infection. They are usually first responders to microbial infection; their activity and death in large numbers forms pus.

In the proliferative disorders there is an increase in the number of white blood cells. This increase is commonly reactive (ex. due to infection) but may also be cancerous. In leukopenias there is a decrease in the number of white blood cells.

1 Thrombocytopenia-a decrease in the number of platelets (PLT), which may lead to low blood platlet count. 2  Leukopenia-a decrease in the total number of white blood cells (WBC), which may lead to low white blood cell count.

LOW WHITE BLOOD CELL COUNT (low WBC). Leukopenia-A decrease in the total number of white blood cells, which may lead to low white blood cell count. Neutropenia-A decrease in the number of neutrophils, which may lead to low white blood count. Granulocytopenia-Some people use this term in place of Neutropenia.

Specific causes of low white blood cell count include: 1  Aplastic anemia. 2  Certain medications, such as antibiotics and diuretics. 3  Chemotherapy. 4  HIV/AIDS. 5  Hypersplenism, a premature destruction of blood cells by the spleen. 6  Infectious diseases. 7  Kostmann's syndrome, a congenital disorder involving low neutrophil production. 8  Leukemia.

Monocytes and neutrophils are phagocytic. The number of leukocytes in the blood is often an indicator of disease, and thus the WBC count is an important subset of the complete blood count. The normal white cell count is usually between 4 and 11 × 10 9 /L. In the US this is usually expressed as 4,000–11,000 white blood cells per microliter of blood. They make up approximately 1% of the total blood volume in a healthy adult. An increase in the number of leukocytes over the upper limits is called leukocytosis, and a decrease below the lower limit is called leukopenia.
