Introduction

A white blood cell differential test can help assess the body's ability to respond to and fight infection.

The test can also determine the severity of allergic reactions and reactions to medications.

A white blood cell differential test plays an important role in assessing the body's reactions to viral infections and chemotherapy (powerful cancer-killing medication).

The test can also help identify the different stages of leukaemia (cancer of the white blood cells).
