ABSTRACT:
An apparatus for forming a blood droplet of a controlled, generally uniform size from a finger which has been pricked to draw blood includes a "funnel" member providing an upper edge across which the finger is drawn to deposit blood on a surface down which the blood flows under the influence of gravity to a lower edge terminating at a point. The blood flows toward the point, forms into the droplet at the point, and, owing to gravity and the surface tension of the blood, forms into the substantially uniformly sized droplet which falls onto a test strip positioned beneath the point.
