What can the results of a white blood cell differential test indicate

What do the results mean? There are many reasons your blood differential test results may be outside the normal range. A high white blood cell count may indicate an infection, immune disorder, or allergic reaction. A low count may be caused by bone marrow problems, medication reactions, or cancer.

What does white blood cell differential test for?

A white blood cell (WBC) count measures the number of white blood cells in your blood, and a WBC differential determines the percentage of each type of white blood cell present in your blood. A differential can also detect immature white blood cells and abnormalities, both of which are signs of potential issues.

What does it mean when CBC with differential abnormal?

Abnormal results of a CBC differential: Certain medical disorders can cause your bone marrow to produce abnormal counts of white blood cells. Increased number of neutrophils: Your bone marrow may make a higher number of neutrophils if you have a bacterial infection or are experiencing acute stress or trauma.

How is the differential white blood cell count determined?

In the automated differential, a blood sample is loaded onto an analyzer, which samples a small volume of blood and measures various properties of white blood cells to produce a differential count.

What happens if neutrophils are high?

If your neutrophil counts are high, it can mean you have an infection or are under a lot of stress. It can also be a symptom of more serious conditions. Neutropenia, or a low neutrophil count, can last for a few weeks or it can be chronic.

Why is differential WBC count more valuable?

Why is a differential WBC count more valuable than a total WBC count when trying to pin down the specific source of pathology?
