Leukocyte Count: What Do Your WBC Levels Mean?

What are White Blood Cells?

White blood cells (WBCs), also known as leukocytes, are part of your body's immune system. They fight infection and help protect your body from disease. There are several different types of WBCs, each with a specific function.

Normal Leukocyte Count

A normal white blood cell count ranges from 4,000 to 11,000 cells per microliter of blood. However, the normal range can vary slightly depending on your age, sex, and other factors.

High Leukocyte Count

A high white blood cell count, also known as leukocytosis, can indicate an infection or inflammation in the body. Some common causes of leukocytosis include:

• Bacterial infections
• Viral infections
• Fungal infections
• Parasite infections
• Inflammatory conditions
• Certain medications
• Leukemia

Symptoms of High Leukocyte Count

In some cases, a high white blood cell count can cause symptoms such as:

• Fever
• Chills
• Fatigue
• Weakness
• Muscle aches
• Headache
• Nausea
• Vomiting

Low Leukocyte Count

A low white blood cell count, also known as leukopenia, can indicate a problem with your immune system. Some common causes of leukopenia include:

• Viral infections
• Certain medications
• Chemotherapy
• Radiation therapy
• Autoimmune disorders
• Bone marrow disorders

Symptoms of Low Leukocyte Count

In some cases, a low white blood cell count can cause symptoms such as:

• Frequent infections
• Severe infections
• Fatigue
