A CBC or complete blood count is done under the microscope. The number of red blood cells is determined as well as the hemoglobin. The number of white cells is determined, which can indicate infection. Then a differential is done to see what type of white cells are present and in what ratio. (lymphocytes, leucocytes, monocytes, etc.) Platelets are counted which help in blood clotting. As answer 1 said, there are whole courses in college on this.

A complete blood count measures the total number of red blood cells, white blood cells and platelets in a standard volume of blood, in addition to the entire hemoglobin content. A variety of different indices are calculated using the above numbers. The infomation gathered can give the doctor a lot of information.
A smear of the blood is placed on a slide, stained and examined microscopically to see if there is any abnormality in the red blood cells, or white blood cell lines or their development.
Entire chapters have been written in books detailing this. How much or how detailed info are you seeking?
