What is the normal ANC?

• A. 2.5-7.0 x10^9/L.
• B. 1.0-2.0 x10^9/L.
• C. 0-1.0 x10^9/L.
• D. 4.0-9.0 x10^9/L.

Answer: (A)

Absolute neutrophil count represents how many neutrophils are present in a liter of blood, and it’s a key measure of the body's immediate defense against bacterial infections. The normal range for adults is about 2.5 to 7.0 x10^9/L, a level that means there are enough neutrophils to respond quickly to invading bacteria. When the ANC falls below this range, neutropenia occurs, increasing infection risk; when it rises above this range, neutrophilia can be seen with infection, inflammation, or stress. While some labs use slightly different reference intervals, 2.5–7.0 x10^9/L is a common and clinically typical normal value for the ANC.
