CBC / Hematology
Also known as: ANC, Absolute Neutrophil Count
If your neutrophil count is very low (severe neutropenia), you may be at high risk for serious infections. Contact your doctor immediately if you have a fever, chills, or any signs of infection, as urgent medical attention may be needed.
This test counts neutrophils. Neutrophils are a kind of white blood cell. They help your body fight off infections caused by bacteria.
Your doctor orders this test for many reasons. They might want to see if you have an infection. They may also check for swelling or irritation in your body. This test can show how certain medicines affect you. It can also help find problems with your immune system. Sometimes, doctors use it to figure out why you have a fever. It can also help explain unusual white blood cell counts.
Reference ranges for absolute neutrophil count can vary by laboratory. Your doctor will interpret your results based on the specific reference range used by the lab that performed your test, as well as your age, sex, and overall health.
