The differential count gives us information on the number of different types of leukocytes in per 100 leukocytes.

The smear is made on the slide. First of all a drop is put on a slide. Then with the help of another slide the smear is prepared. The cells are counted one by one. No special slide like counting chamber or dilution fluids.

The cells are differentiated on the basis of nuclear lobes they contain. And the staining capacities of granules present in the cytoplasm.
