White blood cells (WBCs) or leukocytes. are . the colorless and nucleated formed elements of blood (. leuko. = white or colorless). Compared to RBCs, the WBCs are larger in size and lesser in number. Yet functionally, these cells . A blood film is stained with Leishman’s stain and scanned under oil immersion, from one end to the other. . As each WBC is encountered, it is identified until 200 leukocytes have been examined. . The percentage distribution of each type of WBC is then calculated. . 1.
