An improved method and apparatus for making blood smears on microscope slides are disclosed. The method is characterized by the step of temporarily deforming the normally planar surface of a slide on which the smear is being made, rendering it slightly concave in shape. This step has been found to substantially reduce streaking and other artifacts which interfere with the formation of an uninterrupted, substantially uniform monolayer of blood cells on the slide. Preferably, the movement of a blood-smearing member across the slide is controlled as a function of various predetermined physical parameters of the blood.

A method for making an examinable smear of a biological fluid on a microscope slide having a pair of opposing planar surfaces, said method comprising the steps of: depositing a drop of biological fluid on a planar surface of a microscope slide; applying a vacuum force to the planar surface of said slide opposite the drop-receiving surface to deform said drop-receiving surface in a direction away from said drop to render said surface concave; spreading said drop in a predetermined direction across the deformed surface of said slide to produce said smear.
