The ISTH group produced a simple scoring system for the diagnosis of DIC depending on the Platelet count, the PT, the fibrinogen level and critically the FDP/D-Dimer results:
| Parameter | Result | Score |
| 1. Platelet count |
>100×109/l <100×109/l < 50×109/l |
0 1 2 |
| 2. PT |
<3s prolonged >3s but <6s >6s |
0 1 2 |
| 3. Fibrinogen |
>1.0g/l <1.0g/l |
0 1 |
| 4. FDP/D-Dimer |
No increase Moderate increase Strong increase |
0 2 (250-5,000) 3 (>5,000) |
