Tests used for disseminated intravascular coagulation (DIC) include:

Tests used for disseminated intravascular coagulation (DIC) include:

• A. Fibrin Split, Fibrin degradation, D-dimer
• B. Platelet count, Hemoglobin, Blood glucose
• C. PT, INR, aPTT
• D. ESR, CRP, Serum ferritin

Answer: (A)

In DIC, the body forms clots throughout the bloodstream and then breaks them down more rapidly than normal, leading to a surge of fibrin degradation products. Measuring these products directly captures the active fibrinolysis that accompanies DIC. Fibrin degradation products and D-dimer rise as clots are continuously formed and dissolved, so they are the most direct indicators of the process at work in DIC. Other tests shown—such as general coagulation times (PT/INR/aPTT) or routine labs like platelet count, hemoglobin, glucose, or inflammatory markers—can be abnormal in DIC but do not specifically reflect the fibrinolytic breakdown of clots. They’re useful pieces of the overall picture, but the presence of fibrin split products and D-dimer best captures the hallmark enzymatic activity of DIC.
