Casos de Uso
- •Diagnosing overt DIC in patients with underlying conditions.
- •Serial monitoring of coagulopathy progression.
- •Guiding anticoagulation and supportive therapy in DIC.
Fórmula
ISTH DIC Score = Platelet count(0-2) + D-dimer(0-3) + PT prolongation(0-2) + Fibrinogen(0-1). Score ≥5 = overt DIC.
Preguntas Frecuentes
What is the ISTH DIC score?
The International Society on Thrombosis and Haemostasis (ISTH) DIC score is used to diagnose overt disseminated intravascular coagulation. It uses four laboratory parameters: platelet count, D-dimer/fibrin degradation products, prothrombin time, and fibrinogen.
How is the DIC score interpreted?
Score ≥5: Overt DIC — compatible with DIC diagnosis; repeat daily. Score <5: Non-overt DIC — may be pre-DIC state; repeat within 1–2 days if clinically suspected.
