[摘要]目的比较两种检测抗CCP抗体方法的优劣。方法用胶体金法与ELISA法对患者血清进行抗CCP抗体检测,两种方法结果不符的以临床明确诊断确认。结果胶体金法灵敏度85%,特异性为97.5%,假阳性率2.5%,假阴性率为15%;同ELISA法比较得出阳性符合率为98.8%,阴性符合率为98.4%。结论两种检测方法的灵敏度和特异性无差异,均较高,

Abstract[]Objective To compare two methods to determine anti-CCP antibody for diagnosis of RA.Methods The serum anti-CCP antibody was detected with methods of GICA and ELISA, and their respective sensitivity and specificity were compared and the results were confermed with the clinical diagnosis.Results The sensitivity and specificity of anti-CCP antibody with the method of GICA were 85% , 97.5%.The false-positive and false-negative were 2.5%, 15%.The rates of positive and negative coincidences were 98.8%, 98.4%, respectively compaired with ELISA.Conclusions The sensitivity and specificity difference of two methods had no statistical significance.

类风湿关节炎( rheumatoid arthritis, RA)是常见的自身免疫性疾病,以关节滑膜慢性炎症为主要表现。目前抗环瓜氨酸肽(anti- cyclic citrullinated peptide,抗CCP)抗体的检测方法为酶联免疫吸附法(enzyme-linked immunoabsorbent assay , ELISA)[1],因其检测试剂对环境及保存条件的限制,在基层医院的检验科和门诊中较难实现该项目的实验检测。胶体金免疫层析法(goldimmunochromatography assay,GICA)因对试剂保存条件与实验室环境要求不高,而且,试剂包装简易,可以单独对一份标本进行试验,其操作简便、快速,结果直观,稳定性好等,应用于抗CCP抗体检测,可快速筛选类风湿性关节炎,使类风湿性关节炎的早期诊断变成现实;满足基层医院、即时检测、床边检测的需求,将拥有巨大的市场潜力和效益[2]。该文以2013年6月—2014年7月收集的200例RA患者为研究对象,对两种诊断产品的临床检测性能进行评估研究,报告如下。
