Abstract Objective To study the predictive results of blood culture results by quantitative detection on serum PCT. Methods From January 2014 to December 2015，the clinical data of 500 patients for whom were treated in our hospital，at the same time the blood culture and quantitative detection of serum PCT were tested.The clinical data of patients with PCT were detected and the results were effective and retrospectively studied.The results of blood culture and serum PCT in 500 children were tested and analyzed.The sensitivity，specificity，positive predictive value and negative predictive value of PCT in blood culture were analyzed.Results 500 children with blood culture results in 125 cases with positive，including 113 cases of bacterial infection and 12 casesof fungal infection，375 caseswith negative；125 children with positive in PCT detection were showed 108 cases positive，including 97 casesofbacterial infection and 11 cases of fungal infection，the positive predictive valuewas 86.4%，the negative predictive value was 43.47%；using 0.05μg/L as the cut-off value，the sensitivity of PCT on blood culture with 70.25%，specificity with 56.67%，positive predictive value with 28.55%，negative predictive value with 91.56%.Conclusion The quantitative detection of serum PCT can help to diagnose the bloodstream infection in children quickly.If it can be combined with clinical observation and analysis，the detection ratewill improve.
