Neutrophil Count (Absolute)

Why This Test Is Done

Doctors may order an absolute neutrophil count to diagnose or monitor conditions like infections, certain cancers (e.g., leukemia), autoimmune diseases, or after treatments that weaken the immune system. It can also help assess how well your body is recovering from surgery or illness.

What to Expect Before the Test

You won’t need special preparation. The test is usually done by drawing blood from a vein in your arm. It takes a few minutes, and you may feel a slight pinch, but it’s generally quick and painless. Avoid heavy exercise or stress before the test if your doctor advises it.

What the Results Mean

Results are reported as the number of neutrophils per microliter (µL) of blood. A normal range varies by lab, but low counts (below 1,500–2,000 µL) may indicate immune suppression, while very high counts (above 8,000–10,000 µL) could signal infection, inflammation, or other conditions.

Common Conditions Affecting Neutrophils

Low neutrophil counts can occur with conditions like aplastic anemia, chemotherapy, or severe infections. High counts may be linked to chronic infections, certain cancers, or inflammatory diseases. Your doctor will interpret results in the context of your overall health and symptoms.
