Claim Text:
1. A method for determining a patient's response to a P2Y12 antagonist, comprising the steps of: providing a platelet-containing blood sample from a patient an individual treated with a P2Y12 antagonist; contacting the platelet-containing blood sample with adenosine diphosphate (ADP), prostaglandin E1 (PGE1) and particles comprising a GPIIb/IIIa receptor ligand, under conditions suitable for platelet aggregation as measured by agglutination of the particles, measuring the level of particle agglutination; determining the level of platelet aggregation as measured by the level of particle agglutination; wherein a reduced level of agglutination, as compared to a control level, indicates an effective response to said P2Y12 antagonist treatment.
