Why is this test done?

Your doctor may order this test to check for infections, inflammation, or other conditions that affect your immune system. It can also help diagnose or monitor certain blood disorders, such as leukemia or other blood cell abnormalities.

What does a high or low neutrophil count mean?

A high neutrophil count may indicate an infection, inflammation, or other health issues like autoimmune diseases or certain cancers. A low neutrophil count can make you more susceptible to infections, which is often seen in conditions like aplastic anemia or certain immune disorders.

How is this test performed?

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

What should you do before the test?

No special preparation is usually needed. However, inform your doctor about any medications you are taking, as some can affect your blood cell counts.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Clinical significance: Neutrophils are a critical component of the immune system. Elevated levels often signal active infection or inflammation, while decreased levels may indicate immune suppression or bone marrow disorders.

Short name
