ABSTRACT:
Platelet activation is measured by determining Mean Platelet Component (MPC) of suspended blood platelets, using a specific anticoagulant composition. The composition comprises at least one component for effecting platelet sphering (for example EDTA), and at least one platelet antagonist (for example at least one of, and preferably all three of theophylline, adenosine and dipyridamole).
