Patent ID: 8883510

Claim:
A method for determining an adhesion disorder or an aggregation disorder, comprising the steps of: activating a platelet-containing sample fluid; measuring a vibration parameter of a resonator with respect to time, said resonator having a measuring surface, and, said measuring surface contacts said platelet-containing sample fluid; recording said vibration parameter with respect to time; analyzing a characteristic curve of said recorded vibration parameter with respect to time; determining platelet function based on said analysis of said characteristic curve of said recorded vibration parameter, said platelet function includes the adhesion of platelets and the aggregation of platelets; said step of analyzing said characteristic curve includes determining if said vibration parameter is unchanged with respect to time indicating an absolute platelet dysfunction in regard to both adhesion and aggregation; said step of analyzing said characteristic curve includes determining if said vibration parameters change substantially exponentially with respect to time indicating that said platelets are considered functional in regard to aggregation; said step of analyzing said characteristic curve includes determining if said vibration parameters change substantially linearly with respect to time indicating that said platelet function is dysfunctional in regard to aggregation but is functional in regard to adhesion; and, determining, based on said step of analyzing said characteristic curve, the presence of an adhesion disorder or an aggregation disorder.
