Two push-type peripheral blood smears suitable for characterization of cellular blood elements. Left smear is unstained, right smear is stained with Wright-Giemsa stain.
A blood film—or peripheral blood smear—is a thin layer of
Blood films are made by placing a drop of blood on one end of a slide, and using a spreader slide to disperse the blood over the slide's length.

The monolayer is found in the "feathered edge" created by the spreader slide as it draws the blood forward.
The slide is left to air dry, after which the blood is
Routine analysis of blood in medical laboratories is usually performed on blood films stained with
