Applied Value of NLR Joint Procalcitonin in Differential Diagnosis of Tuberculosis and Community Acquired Bacterial Pneumonia
摘要
Abstract
Objective The applied value of NLR joint PCT in differential diagnosis of tuberculosis and community acquired bacterial pneumonia was discussed.Methods 192 cases of patients with suspected tuberculosis and 205 cases of patients with community acquired bacterial pneumonia were selected from January 2014 to May 2016 in our hospital,whose NLR was calculated and the serum PCT was detected by ELFA technology.The laboratory examination results of two groups of patients and the efficacy of each laboratory examination index in the differential diagnosis of tuberculosis and community acquired bacterial pneumonia were statistically analyzed.Results The lymphocyte count of tuberculosis group was significantly more than the community acquired bacterial pneumonia group(P<0.05),while the white blood cell count,neutrophil count were significantly less than the community acquired bacterial pneumonia group(P<0.05)and the NLR,PCT were significantly lower than that of community acquired bacterial pneumonia group(P<0.05).The area of NLR + PCT in the differential diagnosis of tuberculosis and community acquired bacterial pneumonia under the ROC curve was significantly greater than the WBC count,neutrophil count,lymphocyte count,NLR and PCT(P<0.05).The sensitivity,specificity,positive predictive value,negative predictive value was 87.0%,87.0%,76.4% and 89.0% respectively when the best threshold lower than 6.0,so NLR+PCT can basically exclude pulmonary tuberculosis.Conclusion NLR joint PCT has high applied value in differential diagnosis of tuberculosis and community acquired bacterial pneumonia.关键词
