Abstract：Objective To investigate the diagnostic value of pulmonary ultrasonography ( LUS) combined with plasma calcitonin ( PCT ) and C-reactive protein ( CRP ) in the diagnosis of community acquired pneumonia ( CAP ) . Methods LUS and chest CT were performed in 240 cases of clinically suspected CAP patients at the same time , and we detect the levels of plasma PCT , CRP and WBC count .Taking chest CT results as a diagnostic CAP "gold standard", we analyzed the diagnostic value of LUS examination , serum PCT and CRP detection in the diagnosis of CAP .Results The specificity and sensitivity of CAP were 72.73%and 95.65%, which were diagnosed by LUS .The sensitivity of increased CRP in the diagnosis of CAP was 97.66%, and the specificity was 30.77%.The specificity of increased PCT in the diag-nosis of CAP was 96.15%, and the sensitivity was 42.52%.The sensitivity and specificity of increased WBC in the diag-nosis of CAP were 88.46%and 84.58%, respectively.The diagnostic sensitivity of LUS combined with PCT , CRP and CAP was 99.06%, and the specificity was 92.59%.Conclusion The sensitivity and specificity of LUS combined with serum CAP and PCT detection in diagnosis of CRP are superior to those of single test .
