Abstract
An anticoagulant coating composition suitable for coating the interior surfaces of a blood microsample collection tube, such as a capillary tube, is disclosed. The coating composition consists essentially of ethylene diamine tetracetate held in a matrix of polyvinyl pyrrolidone. Both the ethylene diamine tetracetate and the polyvinyl pyrrolidone are dissolved in a water-alcohol mixture to form a coating composition solution.
