    For the D-dimer assay used at this hospital the diagnostic cut-off value for VTE, which distinguishes a positive from a negative D-dimer result, is 243 ng/mL. All 1819 patients were submitted for diagnostic imaging tests for detection or exclusion of VTE/PE because their D-dimer result was >243 ng/mL.

  • D-dimer test, normal D-dimer level and elevated D

    Conclusion: Although D-dimer testing has a reputation for being very non-specific, an extremely elevated D-dimer is uniquely associated with severe disease, mainly including VTE, sepsis and/or cancer. These results suggest that, even if sharply elevated D-dimers are a seemingly solitary finding, clinical suspicion of severe underlying disease should be maintained.
