    Procedure

    1. Using both a low (4x or 10x) and high (40x) power objective lens, sketch one of each cell type.
    2. Starting with the 10X objective, scan the prepared slide and count at least 50 white blood cells. Do not count platelets of red blood cells. As you count, record the numbers of each cell type in your data table.
    3. Calculate the percentage of neutrophils, lymphocytes, monocytes, eosinophils, and basophils out of the total.
