Under the microscope: blood

[sdekivit]

Actually you need to make a proper dillution first, i can not remember the actual percentages. Remember: 1 cubic mm of blood has over 4.5 milion cells...

it's not needed to dilute the blood. You need 1 drop of blood on a film. Then you can stain them with Wright's stain. The standard method is then to spread out the blood in an angle of about 30 degrees across the film (diluting the bloodcellpopulation on the sides). Then you can search for specific bloodcells where the red bloodcells are just overlying each other (mostly on the sides of the film).
