降钙素原检测及临床应用评价

Determination of procalcitonin and clinical value

降钙素原(PCT)在临床上主要用于细菌感染及其感染程度的判断;同时还可以指导抗生素选择调整及治疗效果的评定。由于其仍然有一定的局限性,因此PCT与其他炎症指标联合检测,能更好地对细菌感染性疾病作出更为准确的诊断。

Procalcitonin（PCT）is useful in the rapid detection and monitoring of bacterial infection.Serial evaluations of this protein seem to be more accurate in the diagnostic phase.PCT can provide information not only about the course of bacterial infection but also useful to predict outcome and response to antibacterial treatment.On the other hand,some issues have yet to be solved and PCT is preferably in combination with other clinical or laboratory tests,and this might be of help in finding early bacterial infections.
