Final answer:
The absolute lymphocyte count can be calculated by multiplying the total white blood cell count by the lymphocyte percentage. It is an important measure to assess the immune response in a patient.
Step-by-step explanation:
The absolute lymphocyte count refers to the actual number of lymphocytes in a given volume of blood. To calculate the absolute lymphocyte count, you need to know the total white blood cell count and the lymphocyte percentage. The formula to calculate the absolute lymphocyte count is:
Absolute Lymphocyte Count = Total White Blood Cell Count x Lymphocyte Percentage
For example, if the total white blood cell count is 10,000 cells/µL and the lymphocyte percentage is 30%, then the absolute lymphocyte count would be 10,000 cells/µL x 0.30 = 3,000 cells/µL.
