Good to knowOne result rarely tells the whole story. Your provider looks at your results together with your symptoms, exam, and other tests.
What the test is
It's part of a CBC with differential.
Some healthy people, including many of African or Middle Eastern descent, naturally have lower counts without higher infection risk.
Why it's done
- Fever or infections
- During chemotherapy or with medicines that lower counts
Getting ready and what happens
- None.
How the test is done
- A health worker cleans the skin, puts a band around your arm, and draws blood from a vein with a small needle. It takes a few minutes.
What the results mean
| Result | Typical range for adults |
|---|---|
| ANC | About 1,500 to 8,000 per microliter |
| Severe neutropenia | Below 500 per microliter |
Normal ranges vary from lab to lab and can differ by age, sex, and pregnancy. Your report lists your lab's own range next to each result. A result a little outside the range is often not a problem.
Low
Raises infection risk. Causes include viral infections, medicines, chemotherapy, and marrow problems.
High
Common with bacterial infections, stress, smoking, and steroids.
When a result needs quick action
Call 911Fever of 100.4°F or higher with an ANC below 500
Questions to ask your provider
- What do my results mean for me?
- Do I need to repeat this test or have other tests?
Risks
A blood draw is very safe. You may have slight pain or a small bruise where the needle went in.
