Accuracy of D-dimer : fibrinogen ratio to diagnose pulmonary thromboembolism in patients admitted to intensive care units : cardiovascular topic

Abstract

For diagnosis of PTE, DDFR can be considered to have almost the same importance as D-dimer level. Moreover, it was possible to rule out PTE with only a D-dimer cut-off value < 0.43 mg/dl, without the use of DDFR. However, these values cannot be used as a replacement for angiography or CT angiography.
