Why Is This Test Done?

Your doctor may order this test to check for infections, blood disorders, or immune system issues. It’s often used alongside other blood tests to diagnose conditions like leukemia, autoimmune diseases, or severe infections.

What to Expect Before the Test

No special preparation is needed. You’ll have a small needle inserted into your arm or hand to draw blood. The process usually takes a few minutes, and you may feel slight discomfort.

What the Results Mean

Results are compared to standard ranges for healthy adults. Very low counts may indicate infections, bone marrow problems, or immune deficiencies. Very high counts could suggest infections, inflammation, or other conditions.

Common Conditions Linked to Neutrophil Counts

Low neutrophil counts (neutropenia) can make you more prone to infections, especially bacterial ones. High counts may signal chronic infections, inflammation, or certain cancers. Your doctor will interpret results in the context of your overall health.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Neutrophils are the body’s first responders to bacterial infections. They’re also involved in inflammation. Abnormal counts can signal underlying health issues that require further medical evaluation.

Short name

Absolute Neutrophil Count (ANC)

Frequently asked questions

What causes low neutrophil counts?
Low neutrophil counts can result from infections, certain medications, autoimmune diseases, or conditions affecting bone marrow production. Chronic illnesses like kidney disease or liver disease may also play a role.
What causes high neutrophil counts?
High neutrophil counts often appear during acute infections, severe inflammation, or stress. Some cancers, like leukemia, can also increase neutrophil production.
How often should I get this test?
Your doctor will determine how often to check your neutrophil count based on your symptoms, medical history, and treatment plan. Regular monitoring may be needed if you have ongoing health conditions.
