White blood cells, also known as leukocytes, play a vital role in the body’s immune system. They help to fight off infections and diseases by attacking and destroying foreign substances, such as bacteria, viruses, and other pathogens. A high white blood cell count, also known as leukocytosis, can be an indication of an underlying infection, inflammation, or disease. In this article, we will delve into what doctors do when your white blood cell count is high, the possible causes of elevated white blood cell counts, and the various treatment options available.
Causes of Elevated White Blood Cell Counts
Elevated white blood cell counts can be caused by a range of factors, including infections, inflammatory diseases, and certain types of cancer. When the body detects the presence of a foreign substance, it responds by producing more white blood cells to fight off the infection. This can lead to a temporary increase in white blood cell count. However, in some cases, a high white blood cell count can be a sign of a more serious underlying condition.
Infections and Inflammatory Diseases
Infections, such as pneumonia, tuberculosis, and sepsis, can cause a significant increase in white blood cell count. Inflammatory diseases, such as rheumatoid arthritis, lupus, and inflammatory bowel disease, can also lead to elevated white blood cell counts. In these cases, the body’s immune system is overactive, producing more white blood cells to fight off the perceived threat.
Common Infections that Cause Elevated White Blood Cell Counts
Some common infections that can cause elevated white blood cell counts include:
- Pneumonia

What is an elevated white blood cell count, and what does it indicate?
An elevated white blood cell count, also known as leukocytosis, is a condition where the number of white blood cells in the blood exceeds the normal range. This can be a temporary response to a variety of stimuli, including infection, inflammation, or stress. White blood cells, also known as leukocytes, are an essential part of the immune system, and their primary function is to defend the body against pathogens and foreign substances. An elevated white blood cell count can be an indicator of an underlying condition that requires medical attention.
The normal range for white blood cell count varies slightly depending on the laboratory and the individual, but generally, it ranges from 4,000 to 11,000 cells per microliter of blood. A count above 11,000 cells per microliter is considered elevated. It is essential to note that an elevated white blood cell count can be caused by various factors, including viral or bacterial infections, autoimmune disorders, or bone marrow disorders. In some cases, it can also be a sign of a more severe underlying condition, such as leukemia or lymphoma. Therefore, it is crucial to consult a healthcare professional for proper diagnosis and treatment if an elevated white blood cell count is detected.
What are the common causes of elevated white blood cell counts?
There are several common causes of elevated white blood cell counts, including infections, inflammation, and allergic reactions. Bacterial infections, such as pneumonia or tuberculosis, can cause a significant increase in white blood cell count. Viral infections, such as the flu or mononucleosis, can also lead to an elevated white blood cell count. Additionally, inflammatory conditions, such as rheumatoid arthritis or Crohn’s disease, can cause an increase in white blood cell count. Allergic reactions, such as anaphylaxis or asthma, can also trigger an elevation in white blood cell count.
Other causes of elevated white blood cell counts include bone marrow disorders, such as leukemia or myeloproliferative neoplasms, and autoimmune disorders, such as lupus or multiple sclerosis. Stress, smoking, and certain medications, such as corticosteroids or lithium, can also contribute to an elevated white blood cell count. In some cases, an elevated white blood cell count can be a normal response to a physiological stress, such as intense exercise or menstruation. However, if an elevated white blood cell count persists or is accompanied by other symptoms, it is essential to consult a healthcare professional to determine the underlying cause and develop an appropriate treatment plan.
How is an elevated white blood cell count diagnosed?
Diagnosing an elevated white blood cell count typically involves a physical examination, medical history, and laboratory tests.
