<p>A method is provided for measuring inhibition of platelet aggregation by a thrombin receptor antagonist. First, a blood sample is obtained from a patient treated with a thrombin receptor antagonist. The blood sample is mixed in combination with particles including an immobilized GPIIb/IIIa receptor ligand and a thrombin receptor activator. The combination is then incubated under conditions suitable for agglutinating the particles, and platelet-mediated agglutination is assessed in the mixture. The absence of agglutination indicates that the patient has reduced ability to form platelet thrombi in response to the thrombin receptor antagonist treatment. Also provided is a kit for measuring inhibition of platelet aggregation by a thrombin receptor antagonist that includes a GPIIb/IIIa receptor ligand immobilized on a particle, a thrombin receptor activator, an anticoagulant, and a buffer to maintain the anticoagulated blood in a condition suitable for platelet aggregation.</p> |
