Clinical significance: 

Euglobulin clot lysis time (ECLT) provides an overall assessment of the fibrinolysis system by measuring the time for an in vitro clot to dissolve in the absence of the normal plasmin inhibitors. ECLT is useful in assessing the fibrinolytic system and monitoring patients on urokinase or streptokinase fibrinolytic therapy.
