A high white blood cell (WBC) count, also known as leukocytosis, is a condition where the body produces more white blood cells than normal. White blood cells are a crucial part of the immune system, helping to fight off infections and diseases. However, an elevated WBC count can be a sign of an underlying health issue.
What is a normal WBC count?
The normal range for WBC count in adults is typically between 4,000 to 11,000 cells per microliter (µL) of blood. However, this range can vary slightly depending on the laboratory and the individual’s overall health. In children, the normal range is slightly higher, typically between 5,000 to 15,000 cells/µL.
Causes of a high WBC count
There are several reasons why a person may have a high WBC count, including:
- Infections: Bacterial, viral, or fungal infections can cause the body to produce more WBCs to fight off the invading organisms.
- Inflammation: Conditions such as arthritis, inflammatory bowel disease, or other inflammatory disorders can lead to an increased WBC count.
- Allergic reactions: Allergic reactions, such as anaphylaxis, can cause a rapid increase in WBC production.
- Cancer: Certain types of cancer, such as leukemia or lymphoma, can cause an elevated WBC count.
- Bone marrow disorders: Conditions such as myeloproliferative neoplasms or bone marrow failure can lead to an overproduction of WBCs.
- Medications: Certain medications, such as corticosteroids or immunosuppressants, can affect WBC production.
- Stress: Physical or emotional stress can cause a temporary increase in WBC count.
- Pregnancy: Pregnancy can cause a mild increase in WBC count due to the body’s natural inflammatory response.
Symptoms of a high WBC count
In many cases, a high WBC count may not produce any noticeable symptoms. However, if the underlying cause is an infection or inflammation, symptoms may include:
- Fever
- Chills
- Fatigue
- Headache
- Sore throat
- Cough
- Shortness of breath
- Abdominal pain
- Joint pain or swelling
Diagnosis and treatment
To diagnose the cause of a high WBC count, a healthcare professional will typically perform a physical examination, take a medical history, and order laboratory tests, such as:
- Complete blood count (CBC): A CBC measures the levels of different blood cells, including WBCs.
- Blood cultures: Blood cultures can help identify the presence of bacteria or other microorganisms.
- Imaging tests: Imaging tests, such as X-rays or CT scans, can help identify any underlying infections or inflammation.
- Bone marrow biopsy: A bone marrow biopsy may be necessary to diagnose certain bone marrow disorders.
Treatment for a high WBC count depends on the underlying cause. If the cause is an infection, antibiotics or antiviral medications may be prescribed. If the cause is inflammation or an allergic reaction, corticosteroids or other anti-inflammatory medications may be used. In cases of cancer or bone marrow disorders, treatment may involve chemotherapy, radiation therapy, or other targeted therapies.
Example of how a high Wbc count can affect daily life
Meet Sarah, a 35-year-old mother of two who recently discovered she had a high WBC count. Initially, she didn’t experience any noticeable symptoms, but as the days went by, she began to feel fatigued, had frequent headaches, and experienced joint pain. Her healthcare provider diagnosed her with a mild infection and prescribed antibiotics. After completing the treatment, Sarah’s WBC count returned to normal, and her symptoms subsided. However, she learned the importance of regular health check-ups and taking proactive measures to maintain a healthy immune system.
