A patient’s blood cell count shows 15,000 white blood cells (WBCs) per µL of blood. A normal WBC count is about 9,000 cells/µL (the normal range is actually 4,000 to 11,000 WBCs/µL). What percent of normal is this particular patent’s WBC count?

15000/9000 = 15/9 = ?

To calculate the percentage of the patient's WBC count compared to the normal range, you can use the following formula:

Percentage = (Patient's WBC count / Normal WBC count) * 100

In this case, the patient's WBC count is 15,000 cells/µL, and the normal WBC count is about 9,000 cells/µL.

Percentage = (15,000 / 9,000) * 100

Now, let's calculate the percentage:

Percentage = 1.67 * 100

Percentage ≈ 167%

Therefore, the patient's WBC count is approximately 167% of the normal range.
