What Is a White Blood Cell (WBC) Count?

By LabBee | 2022  5-minute read 

White blood cell count refer to the number of white blood cells in your body.

WBC or white blood cell (WBC) count is a test that measures the number of white blood cells in your body. This test is often included with a complete blood count (CBC), commonly used to screen for different conditions that may affect your health.

There are several types of white blood cells, and your blood usually contains a percentage of each type. Sometimes, however, your white blood cell count can fall or rise out of the healthy range. This may be due to an underlying condition or infection.

Why do you need a white blood cell count

As we mentioned before WBC is often included on the CBC test as part of a routine blood test

White blood cells or leukocytes, help fight infection by attacking bacteria, viruses, and germs that invade the body.

A white blood cell count can detect hidden infections within your body and alert doctors to undiagnosed medical conditions, such as autoimmune diseases, immune deficiencies, and blood disorders. This test also helps doctors monitor the effectiveness of chemotherapy, radiation treatment, and other therapies in people with cancer.
