What Neutrophil Count Measures

Neutrophils are a key part of your immune system. They are a type of white blood cell that helps your body fight off bacterial infections. This test helps doctors determine if your neutrophil count is too high or too low, which can indicate different health conditions.

Why Your Doctor Might Order This Test

Your doctor may order this test if you have symptoms like frequent or severe infections, fatigue, weight loss, or if you’re recovering from a serious illness. It can also be used to monitor conditions like leukemia, autoimmune diseases, or certain infections.

How the Test Works

A small blood sample is taken from a vein, usually in your arm. The sample is then analyzed to count the number of neutrophils in your blood.

What to Expect Before the Test

There are usually no special preparations needed for this test. You may have some mild discomfort from the needle, but it’s a quick and common procedure.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

High neutrophil counts may suggest infections, inflammation, or certain cancers. Low neutrophil counts can indicate immune deficiencies, bone marrow disorders, or side effects from medications. Your doctor will interpret the results in the context of your overall health and symptoms.
