Which range represents the typical percentage of neutrophils in circulating white blood cells?

• A. 2-5%
• B. 45-75%
• C. 25-40%
• D. 1%

Answer: (B)

Neutrophils are the most abundant white blood cells in circulating blood, so they make up the largest portion of the white cell differential. In adults, their typical share is roughly the majority, commonly around 45-75% of all white blood cells. That’s why this range is the best fit. The other ranges correspond to other leukocytes: 2-5% is typical for eosinophils (and basophils are often around 0.5-1%), 25-40% aligns with lymphocytes, and 1% is far too low for neutrophils. Remember that exact numbers can vary a bit by lab and by age, but neutrophils remain the dominant circulating leukocyte.
