| Japanese Association for Acute Medicine (JAAM) | International Society of Thrombosis and Hemostasis (ISTH) | ||
|---|---|---|---|
| SIRS* criteria | Platelet count | ||
| ≥3 | +1 | <50 × 109/l | +2 |
| 0 to 2 | 0 | ≥50 <100 × 109/l | +1 |
| Platelet count | ≥100 × 109/l | 0 | |
| <80 × 109/l or >50% decrease within 24 hours | +3 | Elevated fibrin-related markera | |
| ≥80 <120 × 109/l or >30% decrease within 24 hours | +1 | Strong increase | +3 |
| ≥120 × 109/l | 0 | Moderate increase | +2 |
| Prothrombin time (value of patient/normal value) | No increase | 0 | |
| ≥1.2 | +1 | Prolonged prothrombin time | |
| <1.2 | 0 | ≥6 seconds | +2 |
| Fibrin/fibrinogen degradation products | ≥3 <6 seconds | +1 | |
| ≥25 mg/l | +3 | <3 seconds | 0 |
| ≥10 <25 mg/l | +1 | Fibrinogen level | |
| <10 mg/l | 0 | <100 g/ml | +1 |
| Diagnosis | ≥100 g/ml | 0 | |
| If, ≥4, there is positive diagnosis of DIC. | Diagnosis | ||
| If >5, there is positive diagnosis of overt DIC. | |||
| If <5, suggestive (not affirmative) for non-overt DIC. | |||
