Table 3 Predictive value of negative IMA (<0.25 ABSU), negative D-dimer (<0.81 μg/ml), CRP ≤ 0.59 mg/dl, Sa02 ≥ 90%, respiratory rate ≤ 20/min, heart rate ≤ 100/min and PH<7.45, alone and in combination for excluding PE diagnosed on the basis of s-CTPA.
From: The value of ischemia-modified albumin compared with d-dimer in the diagnosis of pulmonary embolism
