Abstract:
Objective To evaluate the application value of the blood culture combined with the detection of serum procalcitonin and C-reactive protein(CRP)in diagnosing infectious fever patients.Methods The PCT and CRP detection results on the blood sampling day in 126 cases of fever with positive blood culture and 123 cases of fever with negative blood culture in the emergency department were retrospectively analyzed,and the two sets of data were compared and statistically analyzed by the SPSS 16.0 soft-ware.Results The positive rates of CRP and PCT in 126 cases of positive blood culture were 100% and 100%,the detection values were 26.9-256.8 and 0.25-98.6,the positive rates of CRP and PCT in 123 cases of negative blood culture 95.5% and 15.4% re-spectively,the detection values were 1 .2-126.8 and 0.02-0.98.The PCT and CRP detection values in the positive blood culture group were significantly higher than those in the negative blood culture group,the difference was statistically significant(P <0.01). Conclusion PCT and CRP can be served as the monitoring indicators for blood bacterial infections,the blood culture combined with PCT and CRP detection has the guidance significance for early diagnosing bacterial infection.
