Neutrophil Count (Absolute Neutrophil Count, ANC) in Whole Blood

What Is Neutrophil Count Used For?

Neutrophils are a key part of your immune system. They help your body fight off bacteria and other infections. Your ANC helps doctors determine if your immune system is functioning well, especially if you have conditions like cancer, chemotherapy, or certain infections that may lower your white blood cell count.

Why Might Your Doctor Order This Test?

Your doctor may order an ANC test to check for infections, monitor immune function, or evaluate how treatments like chemotherapy or radiation are affecting your blood cells. It’s also useful before surgeries or if you have symptoms like frequent infections, fever, or fatigue.

How Is the 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 number of neutrophils. This is a quick and painless procedure.

What Are Common Results and What Do They Mean?

Results are typically reported as a count of neutrophils per microliter (µL) of blood. A lower than normal ANC may indicate an increased risk of infections, while a higher than normal count could suggest inflammation or other conditions. Your doctor will interpret the results in the context of your overall health.
