Question

Quizplus · Accepted Answer

The WBC count of 8.3 × 10^9/L falls within the normal reference range of 4.5-11.0 × 10^9/L for adults, indicating a normal leukocyte count. Absolute leukocytosis is characterized by an increase in the total number of leukocytes, usually above 11.0 × 10^9/L, while relative leukopenia refers to a decrease in the percentage of leukocytes within the circulating blood due to an increase in one or more other blood cell types. Absolute leukopenia is characterized by a decrease in the total number of leukocytes below the normal range.
