Abstract
Disseminated intravascular coagulopathy (DIC) is a serious disease with fatal consequences. We prospectively analyzed Innovance <sc>d</sc>-dimer immunoturbidimetric assay in 68 patients diagnosed with DIC on the background of malignancy (22), severe infection (20), or multitrauma (26) at a single institution between January 2010 and January 2011. Median age was 61 years (range 20-89). All patients were assessed according to the International Society of Thrombosis and Haemostasis (ISTH) DIC score. Applying a threshold of Innovance <sc>d</sc>-dimer of 10 mg/L fibrinogen equivalent unit (normal <0.5) was correlated with the highest sensitivity in malignancy (86%) and trauma/surgery (80%) compared to 54% in infection. The specificity remained high at 97% in infection, 81% in trauma and 77% in malignancy with a negative predictive value of 97% in trauma and malignancy, and 88% in infection. Our data suggest that Innovance <sc>d</sc>-dimer is a useful and simple tool that enhances the ISTH DIC diagnostic criteria. Further studies to confirm these findings are warranted.
