Basophils

A blood differential test measures the amount of each type of white blood cell (WBC) that you have in your blood. This test can help diagnose or monitor an infection or condition that affects your immune system.

A blood differential test is often part of a routine checkup. Because the five types of white blood cell do different jobs, measuring them separately can give your health care provider important information about your health.
