1、·醫(yī)學(xué)檢驗(yàn)·2013年11月第20卷第32期ELISA與CMIA檢測(cè)血清中抗一HCV的比較劉艷明湖南省益陽(yáng)市南縣人民醫(yī)院,湖南益陽(yáng)413000【摘要】目的比較酶聯(lián)免疫吸附試驗(yàn)(ELISA)與化學(xué)發(fā)光微粒子免疫分析(CMIA)檢測(cè)血清中丙型肝炎抗體(抗一HCV)的優(yōu)越性。方法首先選擇200份質(zhì)控品對(duì)兩種方法檢測(cè)的準(zhǔn)確性及一致性進(jìn)行分析,然后選擇本院門診及住院患者抗一HCV樣本2000例,分別采用ELISA法與CMIA法對(duì)患者血清中抗一HCV進(jìn)行測(cè)定、分析,并對(duì)比兩種方法對(duì)抗一HCV的陽(yáng)性檢測(cè)率。結(jié)果質(zhì)控品試驗(yàn)結(jié)果:CIMA
2、法與ELISA法檢測(cè)準(zhǔn)確率分別為98.5O%與93.00%,兩種方法檢測(cè)的一致率為93.00%;對(duì)兩種檢測(cè)方法下反饋結(jié)果不一致的樣本進(jìn)行分析,CIMA法檢測(cè)抗一HCV陽(yáng)性結(jié)果為100.O0%,占總樣本數(shù)的1.50%,ELISA法檢測(cè)抗一HCV陽(yáng)性結(jié)果為92.86%.占總樣本數(shù)的6.50%。2000例抗一HCV樣本檢測(cè)結(jié)果:ELISA法陽(yáng)性檢測(cè)率為1.00%,CIMA法陽(yáng)性檢測(cè)率為2.10%,兩種方法抗一HCV陽(yáng)性檢測(cè)率比較,差異有統(tǒng)計(jì)學(xué)意義(P<0-05)。結(jié)論CMIA檢測(cè)抗一I-ICY的準(zhǔn)確率、特異性以及靈敏度均明顯優(yōu)
