Neutrophil count (absolute)

Why is this test done?

Your doctor may order this test to check for infections, inflammation, or immune system problems. It can also help diagnose conditions like leukemia, autoimmune diseases, or infections such as pneumonia or abscesses. Sometimes, it’s used to monitor treatment effectiveness for conditions affecting the bone marrow or immune system.

What does a result mean?

Higher-than-normal neutrophil counts may indicate infections, stress, or certain cancers. Lower-than-normal counts could suggest immune deficiencies, certain infections (like HIV), or conditions affecting bone marrow production. Results are interpreted by your healthcare provider based on your overall health and symptoms.

What should you know before the test?

No special preparation is usually needed, but if you’re on certain medications (like steroids), your doctor may advise adjustments. Avoid heavy exercise or infections before the test if possible. Blood is drawn from a vein, typically in your arm, and the process is quick and usually painless.

How is the test performed?

A healthcare professional will clean your arm and insert a small needle to draw blood. The blood is then sent to a lab for analysis. The test measures the absolute number of neutrophils in your blood sample using automated blood cell counters.
