Combined use of pretest clinical probability score and latex agglutination D-dimer testing for excluding acute deep vein thrombosis

Flow chart summarizes the diagnostic process for deep vein thrombosis (DVT) used in the study. PTP, pretest clinical probability score.

Value of D-dimer assay by pretest clinical probability (PTP) risk classification. Analysis of variance for multiple comparison. *High vs low PTP, P < .0001. #High vs moderate PTP, P = .001. ¶Moderate vs low PTP, P < .0001. The error bars indicate the standard error of mean.

Potential new diagnostic strategy for diagnosis of deep vein thrombosis (DVT) using different D-dimer levels. PTP, Pretest clinical probability score.
