Why Is This Test Done?

Your healthcare provider may order this test to check for infections, inflammation, or other conditions affecting your immune system. It can help diagnose or monitor conditions like bacterial infections, certain blood disorders, or autoimmune diseases.

What to Expect Before the Test

No special preparation is needed. You may have a small needle inserted into your arm to draw blood. If you’re nervous, let your healthcare provider know so they can help make it more comfortable.

What Happens During the Test?

A healthcare professional will take a small sample of blood from a vein in your arm. The blood is then examined under a microscope to count the neutrophils manually.

What Are Normal Results?

There are no specific numeric ranges provided here since they can vary by lab. Your results will be compared to your individual baseline or clinical context.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

High neutrophil counts may suggest infections (especially bacterial), inflammation, or stress. Low counts can indicate immune deficiencies, certain cancers, or severe infections. Your provider will interpret results in relation to your symptoms and medical history.
