These are the 15 most important questions answers about Differential Leucocyte Count that can be asked in interviews for Medical Lab Technicians/ Lab Assistants.

Question 1.What is the full form of DLC?

Answer:- The full form of DLC is Differential Leucocyte Count.

Question 2.How do we report Differential Leucocyte Count?

Answer:- We report Differential Leucocyte Count in the percentage of each type of cell.

Question 3:-How do we calculate the absolute number of cells?

Answer:- First we count each type of cells in 100 cells then we calculate in total leucocyte count and the result is reported in absolute numbers( 10⁹/l).

Question 4.What are the Neutrophils?

Answer:- Neutrophils are white blood cells. They are more than half ( 40% to 80 %) of our circulating white blood cells. They are very important to protect ourselves against infections.

Neutrophils have an average diameter of 12 – 14 um. They have 3 to 5 lobes that are connected by chromatin strands and segmented nucleus. After staining, the cytoplasm of neutrophils is pale pink.

Question 5.What is the normal range of Neutrophils?

Answer:- Normal range :- 40 % to 80 %

Question 6. What are the Lymphocytes?

Answer:-A lymphocyte is a type of white blood cells. Most of the lymphocytes are equal to the size of a red blood cell. Lymphocytes have a dark nucleus with a thin rim of cytoplasm, occasionally containing scanty azurophil granules. Nuclei of lymphocytes are uniform in size and have homogeneous chromatin with some clumping at the nuclear periphery. The size of a lymphocyte is normally about 7-9 um. Some 10 % circulating lymphocytes are larger(10-15 um in size) with more abundant pale blue cytoplasm containing azurophil granules.

Question 7.What is the normal range of Lymphocytes?

Answer:- Normal range :- 20 % to 40 %

Question 8. What are the Monocytes?

Answer:- Monocytes are the largest in size among the circulating leucocytes. They are 15-18 um in diameter. The nucleus of the monocyte is large, curved often in the shape of a horseshoe. The nucleus of the monocyte never undergoes segmentation. They have bluish-grey cytoplasm that contains a variable number of fine granules.

Question 9.What is the normal range of Monocytes?

Answer:- Normal range :- 2 % to 10 %

Question 10. What are the Eosinophils?

Answer:- The size of Eosinophils is 12-17 um in diameter. They have mainly two lobes or segments. The cytoplasm is filled with orange-colored granules. The underlying cytoplasm that is hidden by orange-colored granules is pale blue.

Question 11. What is the normal range of Eosinophils?

Answer:- Normal range :- 2 % to 6 %

Question 12. What are the Basophils?

Answer:- Basophils are large, variable in size, and having blue-black granules of the cytoplasm. They obscure the nucleus.

Question 13. What is the normal range of Basophils?

Answer:- Normal range:- Less than 1%

Question 14. What is ANC?

Answer:- Absolute Neutrophil Count

Question 15. What is AEC?

Answer:- Absolute Eosinophil Count
