Neutrophil Count (Absolute)

Why This Test Is Done

Doctors may order a neutrophil count to diagnose or monitor conditions like infections (such as bacterial infections), certain cancers (e.g., leukemia), autoimmune diseases, or to check how your body responds to treatments like chemotherapy or steroids. It can also help evaluate symptoms like fever, fatigue, or unexplained bruising.

What to Expect Before the Test

This test is usually done by taking a simple blood sample from a vein, often in your arm. You may feel a small pinch, but it’s quick and doesn’t require special preparation. If you’re on blood-thinning medications, let your healthcare provider know before the test.

What the Results Mean

Results are reported as the absolute number of neutrophils per microliter (µL) of blood. Abnormally high or low counts can signal different health issues, but your doctor will interpret results in the context of your overall health and symptoms.

Common Conditions Affecting Neutrophil Counts

High neutrophil counts may indicate infections, stress, or inflammation. Low counts could suggest infections, autoimmune disorders, or certain medications. Chronic conditions like diabetes or kidney disease may also influence neutrophil levels.
