	~~Used~~ to ~~determine~~ pre-test probability ~~when evaluating patients for possible~~ [[pulmonary embolism]].		*Clinical decision tool to estimate pre-test probability of [[pulmonary embolism]]
			*Used to guide diagnostic workup: determines whether [[D-dimer]] alone can exclude PE or if imaging (CTPA) is needed
			*Should be used in conjunction with clinical gestalt and the [[PERC rule]]

			==Interpretation==
			*'''Low probability (score ≤4):''' Obtain [[D-dimer]]; if negative, PE effectively excluded
			**Age-adjusted D-dimer cutoff (age × 10 for patients >50) improves specificity without sacrificing sensitivity
			*'''High probability (score >4):''' Proceed directly to CTPA (D-dimer not useful — high false-negative rate)
			*'''Alternative 2-tier model:''' ''PE unlikely'' (≤4) vs ''PE likely'' (>4)

			==Clinical Application==
			*If Wells ≤4 AND [[PERC rule]] negative → no further testing needed
			*If Wells ≤4 AND PERC positive → obtain D-dimer
			*If Wells >4 → obtain CTPA
