  • Method for determining platelet reactivity in a whole blood sample
    Patent number: 6391568
    Abstract: The present invention provides a method for the quantification and assessment of platelet activation in whole blood samples and monitoring of antiplatelet pharmacologic agents. The method for quantifying platelet activation includes exposing platelets to a physiological concentration of an agonist that activates some of the platelets, resulting in the formation of at least one binding site on the surface of the activated platelets, and measuring the activated platelets. The present invention provides a method of assessing specific components of platelet activation.
