摘　　要：目的:评价时间分辨荧光免疫分析技术(TRFLA)检测乙型肝炎病毒标志物(HBV-M)五项指标(HBsAg、HBsAb、HBeAg、HBeAb、HBcAb)的应用价值。方法:采用TRFIA法对其配套试剂盒进行准确性和重复性测试;然后对108例随机样本采用TRFIA与酶联免疫吸附试验(ELISA)两种方法同时检测HBV-M五项指标;最后对两种方法的差异指标用微粒子酶免疫分析(MELA)法作复核测定。结果:TRFIA检测HBV-M五项指标的准确性和重复性全部符合标准;两种方法检测结果符合率达95.4%以上,各指标阴阳性结果经配对资料x^2检验均差异无显著性(P>0.05);TRFIA与MEIA复核结果高度相符。结论:TRFIA作为一种高灵敏度的定量方法,对HBV-M五项指标的测定,能为乙肝的临床诊断、疗效观察提供动态数据,并为接种乙肝疫苗提供可靠依据,是一种比较理想的定量检测方法。Objective To estimate the value of the time-resolved fluorescence immunoassay（TRFIA） on detecting five im- mun markers （ Hepatitis B surface antigen, Hepatitis B surface antibody, Hepatitis B ＂e＂ antigen, Hepatitis B ＂e＂ antibody, Hepatitis B core antibody） of hepatitis B virus. Methods Measured the accuracy and the duplication by TRFIA for the necessary reagent box;and then, five immun markers of hepatitis B virus of 108 random samples were detected by TRFIA and enzyme linked immunosorbent assay（ ELISE ） ;in the end, reexamined the difference targets of two methods by micro particl enzyme immunoassay（MEIA）. Results The accuracy and the duplication of TRFIA conformed to the standard ;the result＇ s accordant ratio of two methods was above 96.3% ,there was no remarkable significance in the negative targents and positive targents by paired Chi-square test （ P 〉 0.05 ） ;the result of reexamining by MEIA highly accorded with that by TRFIA. Conclusion As a high-sensitive quantitative method on detecting the five immun markers of hepatitis B virus by TRFIA , can provide the dynamic data for clinical diagnosis and the curativ effect observation of hepatitis B , and it can also supply reliable basis for the vaccination of hepatitis B, so it is a perfect quantitative method.
