whats a good power for a microscope for looking at blood smears? also ive been recomended to use a mixture of mehylene blue with eosin to get a good colour contrast, so will the red blood cells just be pink (no nucliei) and while cells will be pink with a blue center and then the plasma will be light pink right? and whats the ratio of white blood cells to red? also is there any other tests i could do on the blood, i think i could do glucose with my grandads deiabitis machine or is that for something else?
