In a differential count of leukocytes showing 55% neutrophils and 3% monocytes, what is the expected number of T cells assuming 85% recovery?

In a differential count of leukocytes showing 55% neutrophils and 3% monocytes, what is the expected number of T cells assuming 85% recovery?

• A. 1500 cells
• B. 2500 cells
• C. 3500 cells
• D. 1700 cells

Answer: (B)

To calculate the expected number of T cells from the provided leukocyte differential count, we start with the total white blood cell (WBC) count. A typical WBC count ranges around 4,000 to 11,000 cells per microliter of blood. For this question, let’s assume a normal WBC count, which we will use as an example to facilitate the calculation. If we assume a total WBC count of 8000 cells/µL, we can first calculate the number of neutrophils and monocytes based on the percentages given in the question. - Neutrophils: 55% of 8000 cells = 0.55 x 8000 = 4400 cells - Monocytes: 3% of 8000 cells = 0.03 x 8000 = 240 cells With this information, we can summarize: Total of neutrophils and monocytes = 4400 cells + 240 cells = 4640 cells. Thus, the remaining percentage of leukocytes would represent other types of leukocytes, including T cells. Since neutrophils and monocytes together account for 58% (55% + 3%), the percentage of other leuk
