White Blood Cell Differential Count

The White Cell Count and Differential test (WBC) measures the number and types of white blood cells in your blood. White blood cells play a critical role in defending the body against infections and other diseases. This test provides insight into the overall health of your immune system and helps identify infections, inflammation, or other blood-related conditions.

Why consider this test?

A change in your white blood cell count or the balance between different types of white blood cells can indicate various health conditions, such as infections, allergies, or blood disorders. This test is used to diagnose infections, monitor the body’s response to treatment, or assess the presence of conditions like leukemia or autoimmune diseases.

Who should get this test done?

• Individuals with symptoms of infection (fever, chills, fatigue)
• People experiencing unexplained weight loss, weakness, or swollen lymph nodes
• Patients being monitored for conditions like leukemia, anemia, or autoimmune diseases
• Those undergoing treatment for infections, cancer, or bone marrow disorders
• Individuals with a weakened immune system, such as those with HIV/AIDS or undergoing chemotherapy

More Information

The test includes a complete white blood cell count and a differential breakdown, which categorizes the white blood cells into specific types: neutrophils, lymphocytes, monocytes, eosinophils, and basophils. The levels and ratios of these cells can help diagnose specific conditions, such as bacterial or viral infections, allergies, or immune system disorders. An EDTA (Ethylenediaminetetraacetic acid) tube is used to prevent blood clotting during testing, ensuring accurate results.
