An apparatus for preparing blood specimens on slides having a test surface comprising guide means, a carrier mounted on the guide means for movement back and forth therealong, the carrier providing means for holding the slide to expose its test surface to receive a drop of blood at a predetermined spot thereon. A member extends toward the path of movement of the carrier preferably but not necessarily to engage the test surface of the slide held thereby. Drive means is provided for moving the carrier at a predetermined speed in one direction along the guide means, the carrier being movable in the opposite direction along the guide means to the point at which such a drop of blood on the said predetermined spot just contacts and wets the said member. The member which engages the slide is preferably a resiliently flexible, thin strip-like member which may be resiliently urged against the test surface of the slide to provide, adjacent the test surface and in contact therewith, a portion of the member which is at least slightly curved about an axis extending generally parallel to the test surface and generally perpendicular to the path of movement of the carrier or which is inclined relative to the test surface.
