If the total WBC count is 9.5 3 10^9/L and there are 37% lymphocytes, what is the absolute count for the lymphocytes?

To find the absolute count of lymphocytes, one needs to multiply the total white blood cell (WBC) count by the percentage of lymphocytes.

The total WBC count given is 9.5 x 10^9/L, which equates to 9.5 billion white blood cells per liter. The percentage of lymphocytes is 37%, which can be expressed as a decimal by dividing by 100, resulting in 0.37.

To calculate the absolute lymphocyte count:

Absolute lymphocyte count = Total WBC count x Percentage of lymphocytes

= 9.5 x 10^9/L x 0.37

= 3.515 x 10^9/L, or when rounded, approximately 3.5 x 10^9/L.

Thus, the absolute count for the lymphocytes is 3.5 x 10^9/L. Recognizing that the absolute lymphocyte count is fundamentally derived from the total WBC count times the decimal form of the lymphocyte percentage confirms the correctness of the calculation.
