Laboratory Evaluation for DVT. D-dimer is often used in non-pregnant patients due to its high negative predictive value. D-dimer less than 500 ng/mL has been shown to have 99% negative predictive value in patients with low and intermediate probability for VTE in the nonpregnant population. Pregnancy limits the usefulness of this test, however, because it decreases specificity of the test.
