Why is this test important?

Your doctor may order this test to check if your immune system is working properly, especially if you have frequent infections, low energy, or signs of infection like fever, swelling, or redness. It can also help monitor conditions like leukemia, autoimmune diseases, or certain infections.

What does a low or high neutrophil count mean?

A low neutrophil count (neutropenia) may indicate an overactive immune system attacking your own cells, infections, or certain medications. A very high count (neutrophilia) could suggest chronic inflammation, infections, or other underlying health issues.

How is this test done?

A small amount of blood is drawn from a vein, usually in your arm. The blood is then analyzed in a lab to count the neutrophils.

What can affect neutrophil counts?

Several factors, including infections, stress, certain medications (like chemotherapy), autoimmune diseases, or even diet, can influence neutrophil levels. Recent illness, surgery, or even sleep deprivation may temporarily affect results.
