Fibrinolysis Profile II (Esoterix)
Use
The Fibrinolysis Profile II (Esoterix) test is used to assess various components of the fibrinolytic system, which is the body's process of breaking down clots. This test evaluates the levels and activity of key fibrinolytic markers and proteins, helping in the diagnosis and management of disorders involving excessive clotting or bleeding. It includes the measurement of alpha-2 antiplasmin, D-dimer, euglobulin lysis time, fibrin degradation products, plasminogen activator inhibitor 1 activity, plasminogen activity, and tissue plasminogen activator antigen.
