An integral device for preparing a smear of blood or other sample on a glass slide or other surface is disclosed. The device includes as an operatively integral structure an elongate reservoir having a tip at one end for drawing blood into the reservoir, for example by capillary action or aspiration, and delivering controlled quantities of blood from the reservoir to a slide. Attached to the opposite end of the reservoir a smearing device has an edge cooperable with the surface of the slide to smear blood deposited by the tip. Using the device, a person would manually hold the same in position to draw blood via the tip into the reservoir, would then manipulate the device to deposit a quantity of blood onto the surface of a slide, and while still holding the device would turn the same to place the smearing edge in contact with the slide and would effect relative movement therebetween to smear the blood.
