A20 to 30 percent
B50 to 70 percent
CUnder 1 percent
D2 to 8 percent
Answer & Solution
Correct answer: D. 2 to 8 percent
1. Monocytes normally represent 2 to 8 percent of the total leukocyte count.
2. They are the largest leukocytes by diameter but not the most numerous.
3. Size and abundance are independent, which is the confusion the 50 to 70 percent option exploits.
4. High monocyte counts point to viral or fungal infection, tuberculosis, some leukemias and other chronic disease.
