Low white blood cell count A low white blood cell count (leukopenia) is a decrease in disease-fighting cells (leukocytes) in your blood. Leukopenia is almost always related to a decrease in a certain type of white blood cell (neutrophil). The definition of low white blood cell count varies from one medical practice to another. In general, for adults a count lower than 4,000 white blood cells per microliter of blood is considered a low white blood cell count. For children, that threshold varies with age.

Neutropenia (Low Neutrophil Count) Neutropenia is a low white blood cell count. Neutrophils are one type of white blood cell. White blood cells help the body fight infection. People with neutropenia have a low number of these white blood cells, so it is harder for their bodies to fight infection.

What Causes A Low Blood Count? A low blood count means that something in your blood is at abnormally low levels, such as red blood cells, white blood cells, hemoglobin or platelets. There are many causes of a low blood count which range the spectrum of medical severity from a simple infection to cancer. Your doctor will diagnose your condition based on your symptoms, your medical history and your low blood cell count.

- 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.

What Causes a Low Blood Count? Infections may cause a temporary decrease in white blood cell count, a condition known as leukopenia. In a severe bacterial infection, white blood cells that normally circulate in the bloodstream migrate to the site of the infection in large numbers, leading to a low white blood cell count in the blood.

- One type of white blood cell is the neutrophil. These cells are made in bone marrow and travel in the blood. They sense infections, move toward the germs, and kill them. It is called a low white blood cell count, or neutropenia, when a person has too few neutrophils.

What Causes Low White Blood Cells? White blood cells together with plasma, platelets and red blood cells, make up your blood system. Your white blood cells serve to protect your body against disease and illness. Even though they make up only 1 percent of your blood, a low count can warn you to find out what causes low white blood cells and how to treat it.

Low white blood cell count and cancer Low white blood cell count and cancer. White blood cells fight infections from bacteria, viruses, fungi. and other pathogens (organisms that cause infection). One important type of white blood cell is the neutrophil. These cells are made in bone marrow and travel in the blood throughout the body.

Leukopenia Causes Medical conditions. Low white cell count may be due to acute viral infections, such as a cold or influenza. It has been associated with chemotherapy, radiation therapy, myelofibrosis, aplastic anemia (failure of white cell, red cell and platelet production), stem cell transplant, bone marrow transplant, HIV, AIDS, and steroid use.

What does a Low White Blood Cell Count Indicate? Unfortunately, the most popular treatments for leukemia and other types of cancer can also result in a low white blood cell count. Chemotherapy and radiation therapy are intended to seek out and destroy abnormal cells, but innocent, healthy white blood cells can also be damaged during treatment.

Low white blood cell count Definition. A low white blood cell count, or leukopenia, is a decrease in disease-fighting cells (leukocytes) circulating in your blood. The threshold for a low white blood cell count varies from one medical practice to another. Some healthy people have white cell counts that are lower than what's considered normal. A count lower than 4,000 white blood cells per microliter of blood is generally considered a low white blood cell count. The threshold for a low white blood cell count in children varies with age and sex.

NCI Dictionary of Cancer Terms White blood cells. White blood cells are part of your immune system. They fight infections. When the number of white cells in your blood is low, you are more likely to get infections because there are fewer white cells to fight off bacteria. If your level of white blood cells is very low you have a high infection risk.hat bone marrow is. Bone marrow is a spongy material that fills the bones. It contains early blood cells, called stem cells. These develop into the 3 different types of blood cell. Normally stem cells in your bone marrow keep dividing to make new blood cells.

Low White Blood Cell Count (Neutropenia) Low White Blood Cell Count (Neutropenia). White blood cells fight infection. A normal white blood cell count is between 5,000 and 10,000 cells. A white blood cell count below 1,000 cells increases the risk of infection.

What Causes a Low White Blood Cell Count? A low white blood cell count is called leukopenia. Leukopenia is best defined as a decrease in the number of white blood cells, called leukocytes, in the blood. The test that determines blood cell count is the white blood cell (WBC) test, which is often included as one part of the complete blood count (CBC) test.
