Question

Quizplus · Accepted Answer

A diff count (differential count) specifically measures the percentages of different types of white blood cells, including neutrophils, lymphocytes, monocytes, eosinophils, and basophils. The CBC (complete blood count) measures the overall white blood cell count but does not differentiate between the different types. The ESR (erythrocyte sedimentation rate) measures the rate at which red blood cells settle out of plasma, which can indicate inflammation in the body. The option "WBC" is not specific enough, as it could refer to either the overall white blood cell count or a specific type of white blood cell.
