May reduce unnecessary ultrasounds in low-probability DVT; leaves open need for prospective validation.
Does clinical probability estimation combined with D-dimer testing accurately exclude deep vein thrombosis?
In patients with a low clinical probability of DVT, a negative D-dimer test safely excludes the diagnosis without requiring an ultrasound.
Philip S. Wells (2006) studied this question.
