In a patient with suspected deep vein thrombosis (DVT), establishing a pre-test probability helps in early risk stratification and appropriate use of laboratory tests and imaging modalities. Many pretest probability scoring systems are proposed for use in primary care patients, such as Wells score, Hamilton score, and AMUSE score; however, the most studied of them is Wells score. When combined with pretest probability, ultrasonography and D-dimer tests are most useful in the diagnosis of DVT.
The Constans score can help diagnose DVT of the upper extremity.
