  • 简介:摘要目的用SEROZYME系统检测血清FT3、FT4并进行临床与实验室考核。方法将本系统与放射免疫法(RIA)进行对比研究。结果健康人(n=68)血清FT3、FT4水平(+SD)分别为4.1±1.1pmol/L、14.1±3.2pmoL/L。甲减组FT4水平下降(P<0.01);FT3水平与正常对照组无显著差异(P>0.05);初诊甲亢组FT3、FT4(P均<0.01)水平升高;糖尿病组FT3水平下降(0.05>P>0.01),FT4水平与正常对照组无显著差异(P>0.05);其它各疾病组两项指标与正常对照组均无显著差异(P均>0.05);与RIA对比检测血清FT3、FT4两法符合率分别达81.5%、74.8%;重复性批内与批间变异系数(CV)FT3分别为2.8%~5.6%、6.8%~9.0%,FT4分别为1.2%~3.4%、4.6%~7.0%;最少检量FT3为0.9pmol/L,FT4为0.1pmol/L;真实性及诊断价值FT3与FT4联合对甲亢、甲减诊断的灵敏度分别为92.2%、90.6%。特异性分别为97.1%、97.1%,总有效率均为95%;阳性预示值分别为95.9%、91.7%;阴性预示值分别为97.1%、95.7%。结论本检测系统对甲状腺功能的诊断灵敏、特异、可靠,与RIA技术相当,或有更多优点。
