Question

Quizplus · Accepted Answer

FDP and D-dimer are breakdown products of fibrin, and increased levels of both are indicative of fibrinolysis. Plasmin is the enzyme responsible for fibrinolysis, but its presence alone does not indicate primary fibrinolysis as it can also occur during secondary fibrinolysis or thrombus remodeling. Fibrinogen and platelet count are not specific for primary fibrinolysis.
