If a WBC count is performed on a 1:100 dilution with 50 cells counted in 8 squares, what is the resulting WBC count?

To calculate the white blood cell (WBC) count based on the described dilution and cell count, the following formula is employed:

WBC Count = (Number of cells counted × Dilution factor × 10) / Number of squares counted.

In this case, a WBC count is performed on a 1:100 dilution, and 50 cells are counted in 8 squares.

1. Number of cells counted: 50 cells.

2. Dilution factor: 1:100, which means you would multiply the count by 100.

3. Number of squares counted: 8 squares.

Substituting the values into the formula:

WBC Count = (50 cells × 100 × 10) / 8 squares

= (500000) / 8

= 62500.

To convert this to the standard count per microliter (µL), note that the count derived from a dilution is typically reported per microliter. Thus, you divide by 1, which gives 62500 cells per µL.

Finally, make sure to review the possible answers provided; the resulting WBC count of 62,500 reflects the typical format used in clinical settings
