In a WBC differential, how are cell types reported?

• A. As a percentage of total 100 cell count.
• B. As an absolute count per microliter.
• C. By color intensity.
• D. As a ratio.

Answer: (A)

A WBC differential presents the relative distribution of white blood cell types as percentages of the total white cells counted. In a manual differential, you typically tally 100 cells and record how many belong to each category (neutrophils, lymphocytes, monocytes, eosinophils, basophils). Those counts become percentages that sum to 100, making patterns of changes in cell populations easy to recognize. If you know the total WBC count from the CBC, you can convert those percentages into absolute numbers per microliter by multiplying by the total—many reports provide these as well. Reporting by color intensity or as a simple ratio isn’t standard for differentials, and absolute counts alone don’t convey the distribution without the context of the total WBC.
