摘　　要：目的：探讨丙型肝炎患者中 HCV-RNA与 HCV-Ab，HCV-cAg三种检测指标的相关性和临床应用效果。方法采用酶联免疫法分别检测实时荧光定量 PCR法检测阳性的140例 HCV患者血清中的 HCV-Ab和 HCV-cAg，以了解检测结果及符合率。结果在140例 HCV-RNA阳性血清中，HCV-cAg 阳性127例，符合率90.71％；HCV-Ab 阳性110例，符合率78.57％；对不同 HCV-RNA浓度的血清进行 HCV-cAg检测结果其阳性检出率随着 HCV病毒含量的升高而增高；不同 HCV-RNA浓度的血清进行 HCV-Ab检测结果无明显变化。结论通过对 HCV-RNA阳性患者中 HCV-Ag和 HCV-Ab的检测观察分析，HCV-cAg检测与 HCV-RNA的检测结果具有较高的符合率。因此 HCV-cAg检测可作为HCV-Ab的补充检测，为 HCV“窗口期”感染以及免疫低下人群感染的筛查提供简便、廉价方法；同时为不具备 HCV-RNA检测条件的基层医疗单位，作为 HCV感染的快速筛查提供诊断依据。Objective To investigate the correlation of HCV-RNA with detection indexes HCV-Ab and HCV-cAg in its clini-cal application effect among patients with hepatitis C.Methods HCV-cAg and HCV-Ab in 140 cases of HCV-RNA were detected by enzyme linked immunosorbent assay in cases of PCR,which were detected by real-time fluorescence quantitative PCR.Results 127 cases in 140 cases of HCV-RNA positive serum were HCV-cAg positive,in line with the rate of 90.71%,and the cases of 110 HCV-Ab positive,in line with the rate of 78.57%.The positive detection rate of HCV-cAg with different HCV-RNA concentration was increased with the increase of HCV virus content,and the serum of different HCV-RNA concentration had no significant changes in HCV-Ab detection results.Conclusion The detection results of HCV-cAg had a high coincidence rate with HCV-RNA.Therefore detection of HCV-cAg can be as a complementary detec-tion of HCV-Ab,as the window period of HCV infection and infection in immunocompromised persons screening provides a simple,inexpensive method.At the same time it provides rapid screening for HCV infection provide diagnostic basis for those basic medical units who do not have the conditions for detection of HCV-RNA.
