Diagnostic Value of Blood Cell Culture and Serum PCT Detection on Bacteremia

Luo Chunwei;The Third Affiliated Hospital of Zhengzhou University;  
Objective To study diagnostic value of blood cell culture and serum procalcitonin(PCT)detection on bacteremia.Methods 80 patients with bacteremia were categorized as observation group,and 80 healthy persons who received physical examination in our hospital during the same period were selected as control group.PCT levels were detected at 24 h,48 h and 72 h of fever in observation group and the same time-point in control group by enzymelinked immunosorbent assay(ELISA).Meanwhile,blood cells were also cultured.The diagnostic efficiencies of blood cell culture,serum PCT level and combined detection in bacteremia were analyzed by ROC curves.Results The positive rates of blood cell culture were 28.75%,57.50% and 95.00% at 24 h,48 h and 72 h of fever.The positive rates of serum PCT at 24 h,48 h and 72 h were 88.75%,97.50% and 100.00% respectively in observation group.The positive rates were 0.00% at every time-point in control group(P0.01).The area under curve,sensitivity and specificity of combined detection in diagnosis of bacteremia were higher than one detection alone(P0.05).Conclusion Blood cell culture and serum PCT level are both diagnostic indicators in the diagnosis of bacteremia.The combination of the two detections is more valuable than one detection alone.
