This version was published as a score, and according to the final score, patients could be categorized in either 3 groups (low / intermediate / high risk) or 2 groups (low / high risk) Subsequent testing choices included D-dimer testing for low risk cases, and V/Q scanning, pulmonary angiography, and compression ultrasonography for intermediate ...
Reference ranges (reference intervals) for blood tests are sets of values used by a health professional to interpret a set of medical test results from blood samples. Reference ranges for blood tests are studied within the field of clinical chemistry (also known as "clinical biochemistry", "chemical pathology" or "pure blood chemistry"), the ...

A D-dimer test can also be used to assist with excluding the diagnosis or to signal a need for further testing. [5] Diagnosis is most commonly confirmed by ultrasound of the suspected veins. [5] VTE becomes much more common with age. The condition is rare in children, but occurs in almost 1% of those ≥ age 85 annually. [3]
The results of these screening tests, in conjunction with the clinical history (especially bleeding history), will then direct the selection of further, more detailed and specific coagulation tests, such as: specific factor assays, like fibrin degradation products, D-dimer, thrombin time, platelet aggregation, or
