a measurement of the amount of plasminogen activator inhibitor 1 (PAI-1)in the blood. PAI-1 is a serine protease inhibitor protein that functions as the principal inhibitor of tissue plasminogen activator (tPA) and urokinase (uPA), the activators of plasminogen and hence fibrinolysis (the physiological breakdown of blood clots).
