Differential Leukocyte Count Quiz

What is the primary advantage of Differential Leukocyte Counting (DLC) over Total Leukocyte Count (TLC)?

• DLC requires less equipment than TLC.

• DLC is faster to perform than TLC.

• DLC offers a percentage breakdown of each type of white blood cell.

• DLC provides a total count of all white blood cells.

Which of the following is NOT required for performing a DLC?

• Blood cell counter

• Stained peripheral blood smear

• Compound light microscope

• Centrifuge

What is the purpose of using immersion oil in the DLC procedure?

• To enhance the visibility of blood cells under high magnification

• To stain the blood smear

• To clean the microscope lens

• To fix the blood smear on the slide

How many types of white blood cells are typically counted in a DLC?

• Three

• Four

• Five

• Six

What is the benefit of using a blood cell counter during the DLC process?

• It automatically stains the blood smear.

• It eliminates the need for a microscope.

• It provides a digital readout of the total leukocyte count.

• It helps in accurately counting and totaling different types of white blood cells.

What is the recommended number of white blood cells to count for reliable DLC results?

• 300 to 400

• 50 to 100

• 100 to 200

• 200 to 300

How is the Relative Differential Leukocyte Count (R DLC) expressed?

• As a percentage

• As a total number of cells

• As a fraction

• As a ratio

What additional information is needed to calculate the Absolute Differential Leukocyte Count (A DLC)?

• The blood sample volume

• The patient's age

• The total leukocyte count

• The percentage of each white blood cell type

Which formula is used to calculate the Absolute Differential Leukocyte Count (A DLC)?

• A DLC = total leukocyte count / percentage of WBC type

• A DLC = percentage of WBC type / total leukocyte count

• A DLC = total leukocyte count x percentage of WBC type

• A DLC = percentage of WBC type x total leukocyte count

What is the normal range of total leukocyte count in a human adult?

• 4,000 to 11,000 cells per microliter

• 16,000 to 20,000 cells per microliter

• 1,000 to 3,000 cells per microliter

• 12,000 to 15,000 cells per microliter
