Test Details & Preparation
An absolute neutrophil count (ANC) can provide your doctor with important clues about your health. An absolute neutrophil count (ANC) is typically ordered as part of a complete blood count (CBC) with differential. A CBC measures the cells that are in your blood.
Your doctor may order an absolute neutrophil count (ANC):
- to screen for a number of conditions
- to help diagnose a condition
- to monitor your status if you have an existing disease or if you’re undergoing chemotherapy
If your absolute neutrophil count (ANC) is abnormal, your doctor will likely want to repeat the blood test multiple times over a period of weeks. This way, they can monitor for changes in your neutrophil count.
What to expect
For the absolute neutrophil count (ANC) test, a small amount of blood will be drawn, usually from a vein in your arm. This will happen at your doctor’s office or in a lab. The blood will be evaluated in a laboratory and the results will be sent to your doctor.
Certain conditions can affect the results of your blood test. Be sure to tell your doctor if you’re pregnant, or if you’ve had any of the following:
Understanding the results
- a recent infection
- radiation therapy
- corticosteroid therapy
- recent surgery
It’s important to have your doctor explain your test results. Results can vary widely from lab to lab. They’re also different depending on:
- your age
- your gender
- your heritage
- how high above sea level you live
- what instruments were used during testing
