The WBC count of a person's blood sample is 8000 /cu.mm. How many eosinophils and lymphocytes would be in the same blood sample approximately ?

Options

  1. A300 - 500 /cu.mm and 1200 - 1500 /cu.mm, respectively
  2. B160 - 240 /cu.mm and 1600 - 2000 /cu.mm, respectively
  3. C300 - 500 /cu.mm and 500 - 700 /cu.mm, respectively
  4. D100 - 120 /cu.mm and 160 - 200 /cu.mm, respectively

Correct answer

B. 160 - 240 /cu.mm and 1600 - 2000 /cu.mm, respectively

Step-by-step solution

Total WBC count = 8000 /cu.mm. Eosinophils constitute 2 - 3 % of total WBCs. Number of eosinophils = 2 100 8000 to 3 100 8000 = 160 - 240 /cu.mm. Lymphocytes constitute 20 - 25 % of total WBCs. Number of lymphocytes = 20 100 8000 to 25 100 8000 = 1600 - 2000 /cu.mm. Answer: 160 - 240 /cu.mm and 1600 - 2000 /cu.mm, respectively
