What is the expected total number of T cells based on a WBC count of 10.0 x 10^3/µL and 40% T cells?

To determine the expected total number of T cells from the provided white blood cell (WBC) count and percentage of T cells, you can use the following formula:

Total T cells = (WBC count in cells/µL) × (Percentage of T cells).

In this case, the WBC count is 10.0 x 10^3/µL, which is equivalent to 10,000 cells/µL, and the percentage of T cells is 40%, or 0.40 when expressed as a decimal.

Now, calculating the total number of T cells:

Total T cells = 10,000 cells/µL × 0.40 = 4,000 cells.

Given that the question asks for the expected number of T cells, it's possible there was a misinterpretation in the options provided, or a detail may need further clarification.

However, if we were to be strictly focused on what the number would translate to in the context of the options given, we could reassess how one might arrive at a figure in the options listed. But fundamentally, the mathematical process highlights that using the WBC count and the percentage yields 4,000 cells, which is not reflected among the options.
