Abstract: A method of monitoring platelet function comprising: passing blood removed from a mammal through a passageway comprising (i) a shear generating restriction to generate a platelet mass in the passageway and (ii) a platelet aggregate trap; and monitoring the flow or composition of the blood in the passageway to detect formation of the platelet mass, wherein the blood passes through the passageway in one direction and only one time. A method of monitoring platelet function comprising: passing blood removed from a mammal through a passageway comprising (i) a shear generating restriction to generate a platelet mass in the passageway and (ii) a platelet aggregate trap; and monitoring the flow or composition of the blood in the passageway to detect formation of the platelet mass, wherein the blood is recirculated through the passageway and the blood flows only one direction through the passageway.

Abstract: The invention provides a method of monitoring platelet function in a mammal by passing blood removed from the body of the mammal through a passageway to contact an obstruction or irregularity in the passageway to generate a platelet mass in the passageway, and monitoring the flow or composition of the blood in the passageway to detect the platelet mass. The flow and composition change in response to the formation of a platelet mass in the passageway. Devices, articles, and kits for performing the methods are also disclosed.
