The PERC (Pulmonary Embolism Rule-out Criteria) rule is an 8-item clinical tool developed to completely rule out PE in patients with a low pre-test probability (<15%). If all criteria are negative, the chance of PE falls below 2%, allowing safe discharge without the need for D-Dimer testing.
The PERC rule MUST only be applied to low-risk patients (Wells score <2 or low clinical gestalt). It is not designed to risk-stratify moderate or high-risk patients; those patients require D-Dimer or CTPA.
