Clopidogrel Response Analysis: Whole Blood Impedance Aggregometry

Whole blood methods that detected platelet aggregation using electrical impedance technology can also be utilized for clopidogrel response testing. In one method, ADP is used as the agonist, typically at a concentration of 5-20 µmol/L. If a patient's test result shows a low response (ADP-induced impedance exceeding 5 Ω (ohms)), it could indicate clopidogrel non-responsiveness.
