Hemocytometer Cell Count Computation

Manual cell counts are performed using a hemocytometer, or counting chamber, and manual dilutions are made with calibrated, automated pipettes and diluents (commercially available or laboratory prepared). The principle for the performance of cell counts is essentially the same for white blood cells (WBCs), red blood cells (RBCs), and platelets; only the dilution, diluting fluid, and area counted vary. A diluted specimen is loaded onto a hemocytometer and the cellular elements are identified and counted microscopically and reported as a number of cells per Liter.

Your video is good but I can't see procedures clearly because they letters are tiny

How do you get 10 or 12 as difference of two counts?

[@KimLesleyQuijano]

How come the numerator is 12 , I tried to calculate the difference between the two counts its only 10. please enlighten me
