DIC Score (ISTH)

Clinically suspected Disseminated Intravascular Coagulation (DIC) in patients with an underlying disorder known to be associated with DIC (e.g., sepsis, trauma, malignancy, obstetric complications).

To objectively verify the presence of overt (decompensated) DIC.

Monitoring disease progression and response to treatment in critical illness.

Non-overt (compensated) DIC — requires a separate scoring system for early phase detection.

Chronic DIC — often seen in malignancy/aneurysms; laboratory parameters may be normal or near-normal despite consumption.

Liver failure — low platelets and high PT may reflect impaired synthesis rather than consumptive coagulopathy (though they often co-exist).
