Actually what I did was to create a tool to help in cell count process. And also will give you some final calculations.

(Wikipedia): Bone marrow examination refers to the pathologic analysis of samples of bone marrow obtained by bone marrow biopsy and bone marrow aspiration. Bone marrow examination is used in the diagnosis of a number of conditions, including leukemia, multiple myeloma, lymphoma, anemia, and pancytopenia. The bone marrow produces the cellular elements of the blood, including platelets, red blood cells and white blood cells. While much information can be gleaned by testing the blood itself (drawn from a vein by phlebotomy), it is sometimes necessary to examine the source of the blood cells in the bone marrow to obtain more...

A little bit more:

The myelogram is the study of a sample of bone marrow obtained by puncture aspiration with proper needle in bones where there hematopoietic activity. The most suitable place for the puncture in children is the iliac crest and the adult sternum. With the puncture material smears are made, stained with Romanovsky mixture and evaluated microscopically. Basically the observation refers to cellularity, which shows us if the marrow is hypo, or hypercellular. The ratio between erythroid and myeloid elements, provides the myeloid - erythroid or M / E, which varies from 2/1 A 4 / 1. We also observed the percentage of lymphocytes fluctuates around 10%, the megakaryocytic series observing the production of platelets and other elements such as parasites and tumor cells. The bone marrow is studied, particularly in anemia, leukemia, purpura, agranulocytosis, myeloma and control of chemotherapy. In addition to analyzing the morphology of the cells, report on a percentage count of 500 cells.

My goal in this project is to help the world of medicine. Mainly on places with less infrastructure or also for those doctors with a microscope at home.
