Rapid D-dimer testing combined with estimation of clinical probability for excluding a diagnosis of DVT*
| D-dimer test result | Estimated clinical probability | 3 month cumulative incidence of DVT (95% CI) |
|---|---|---|
| *DVT = deep venous thrombosis; CI defined in glossary. | ||
| Normal on the SimpliRED D-dimer test | Low | 0.5% (0.07 to 1.1) |
| Moderate | 3.5% (1.4 to 6.9) | |
| High | 21.4% (8.5 to 38) | |
| Normal on the highly sensitive D-dimer tests | Low or moderate | 0.4% (0.04 to 1.1) |
| High | 6.4% (1.7 to 15) | |
