Question

Match each leukocyte to its normal percentage in a differential cell count. A. 50-70% B. 20-40% C. 2-8% D. 1-4% E. < 1% basophils

Answer 1

Answers:

A. 50-70% - neutrophils

B. 20-40% - Lymphocytes

C. 2-8% - monocytes

D. 1-4% - eosinophils

E. < 1% -  basophils

Explanation:

The blood differential test is used to estimate the percentage of each class of white blood cell (WBC) present in the blood and to indicate the presence of abnormal or immature cells.

The Test is Performed by taking of blood sample which is smeared onto a glass slide, then it's stained with a unique dye to indicate the class of white blood cells.

The Five class of white blood cells are

Neutrophils

Lymphocytes (B cells and T cells)

Monocytes

Eosinophils

Basophils

The different class of white blood cells are given as a percentage:

Neutrophils: 40% to 60%

Lymphocytes: 20% to 40%

Monocytes: 2% to 8%

Eosinophils: 1% to 4%

Basophils: 0.5% to 1%

Band (young neutrophil): 0% to 3%
