Answer

Although brain natriuretic peptide (BNP) tests are neither sensitive nor specific, patients with pulmonary embolism tend to have higher BNP levels. BNP testing had a sensitivity and specificity of only 60% and 62%, respectively, in a case-control study of 2213 hemodynamically stable patients with suspected acute pulmonary embolism. [60]
