What Is Neutrophil Count Used For?

Doctors may order this test to diagnose or monitor conditions like infections, autoimmune diseases, or blood disorders. Low counts can indicate immune suppression, while high counts may suggest infection or inflammation.

When Might You Need This Test?

You might need this test if you have symptoms like frequent infections, unexplained fevers, or if your doctor suspects a blood disorder or immune-related condition.

How Is the Test Performed?

A blood sample is taken from a vein, usually in your arm. The sample is sent to a lab where it is analyzed to count neutrophils accurately.

What Do Results Mean?

Results show the number of neutrophils per microliter of blood. Abnormal counts may signal underlying health issues that need further evaluation.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Clinical significance: Neutrophil counts are critical for assessing immune function. Low counts (neutropenia) can increase infection risk, while elevated counts (neutrophilia) may indicate acute infection, inflammation, or other conditions like stress or certain cancers. Regular monitoring helps manage chronic conditions like leukemia or autoimmune diseases.

Short name

Absolute Neutrophil Count (ANC)
