ASSAY BLOOD DRAWING TOOL

PROBLEM TO BE SOLVED: To reduce manufacturing cost and to assay drawing an extremely small amount of blood highly reproducibly in a short time by simple operation by providing a groove-shaped assay part at the top end part of a holding part made of synthetic resin. SOLUTION: The thick assay part 3 is formed at the top end part of the holding part made of synthetic resin, and a groove 4 is formed at the holding part so that the width of the groove 4 from its one end to another end has the same width. In addition, the shape and size of the groove are properly set corresponding to the desired drawing quantity of blood and the kind, property, etc., of synthetic resin constituting an assay blood drawing tool 1 to quantatively draw blood from one μl to several tens μl. At the using time, a finger tip 6 is needled through the use of a lancet to insert the tool 1 into the squeezed blood 5 thereby drawing a fixed quantity of blood. Then, the tool 1 is pressed onto a diagnostic device to execute diagnosis. Thus an extremely small amount of blood is assay drawn highly reproducibly in a short time by simple operation, and also the manufacturing cost is reduced.
