The invention provides for quantitative measurement of an initial platelet activation state. In particular, the invention relates to a platelet activation assay that uses modified prothrombin, which is activated by prothrombinase and which generates thrombin that does not activate platelets but still retains proteolytic activity. In a specific example, prothrombin acetylated with sulfo-N-succinimidyl acetate generates thrombin in the presence of prothrombinase, in which the thrombin lacks platelet activating activity. Thrombin production is detected with a chromogenic peptide cleavage assay.
