Differentiate between absolute and relative concentrations of specific types of leukocytes and give an example of a condition that typically produces abnormal absolute or relative concentrations
What will be an ideal response?
Answer: The relative concentration is the percentage of cells counted in a 100-cell differential. The relative concentration of lymphocytes can be increased when there is neutropenia with a normal WBC.
The absolute concentration is calculated from the total WBC count and the percentage of the particular cell found from the differential count. An absolute lymphocytosis can occur in infectious mononucleosis or other viral infection.
