目的研究降钙素原（procalcitonin，PCT）检测的定量方法和半定量方法检测结果的一致性，为合理选择降钙素原检测方法提供试验依据。方法应用 PCT检测的半定量法（胶体金）和定量法（酶联荧光免疫法）对80例临床标本进行检测，通过直接比较判断检测结果的一致性。结果两种检测方法的结果一致率达到93.75%；当PCT持续高于10ng/ml 时，适合使用定量方法进行监测。结论降钙素原检测的两种方法结果具有一致性，实验室可根据实际情况选择不同的检验方法。“,”Objective To investigate the comparability of the quantitative and semi-quantitative methods for the analysis of procalcitonin and provide experimental basis for the methods. Methods The 80 clinical samples were analyzed by the quantitative and semi-quantitative methods of procalcitonin respectively. The consistency was decided by the direct comparison. Results The concordance rate of the two methods was 93.75%. It's more necessary using way of quantitative analysis for PCT monitoring While the PCT was higher than 10ng/ml consistently. Conclusion The two methods for the analysis of procalcitonin were comparable and the dif erent method could be selected accordingly.
