1、熒光定量PCR檢測(cè)HBV-DNA與乙肝兩對(duì)半檢測(cè)結(jié)果的相關(guān)性探討作者:張蓓,楊曉云,劉蕊,紀(jì)鳳祥【關(guān)鍵詞】常規(guī)檢查;,,HBV-DNA;,,熒光定量PCR 摘要:目的:探討HBV-DNA的檢出情況與乙肝兩對(duì)半結(jié)果之間的關(guān)系。方法:運(yùn)用熒光定量PCR(FQ-PCR)檢測(cè)307例疑似乙肝患者血清中的HBV-DNA,同時(shí)運(yùn)用ELISA方法進(jìn)行兩對(duì)半指標(biāo)的檢測(cè),并對(duì)結(jié)果進(jìn)行相關(guān)性探討。結(jié)果:HBsAg(+)HBeAg(+)HBcAb(+)組(大三陽組)患者血清HBV-DNA檢出率為98.15%(53/54),平均拷貝數(shù)為7.56E+06/ml;H
2、BsAg(+)HBeAb(+)HBcAb(+)組(小三陽組)患者血清HBV-DNA檢出率為27.78%(15/54),平均拷貝數(shù)為3.79E+05/ml;HBsAg(+)HBcAb(+)組血清HBV-DNA檢出率為91.18%(31/34),平均拷貝數(shù)為2.85E+05/ml,小三陽組HBV-DNA陽性檢出率及拷貝數(shù)均低于大三陽組,且與大三陽組比較均具有顯著性差異(P<0.01,P<0.05);HBsAb(+)組血清HBV-DNA檢出率為1.6%(1/63),平均拷貝數(shù)為1.13E+08/ml;HBcAb(+)組血清HBV-DN
3、A檢出率為16.67%(1/6),平均拷貝數(shù)為3.00E+04/ml;HBsAb(+)HBeAb(+)HBcAb(+)組血清HBV9-DNA檢出率為12.50%(4/32),平均拷貝數(shù)為3.00E+05/ml;HBsAg(+)組血清HBV-DNA檢出率為0(0/2);HBV-M全陰性組HBV-DNA檢出率為1.61%(1/62),平均拷貝數(shù)為2.75E+05/ml。結(jié)論:HBV-M陰性患者仍有HBV-DNA陽性者,因此在檢測(cè)中應(yīng)聯(lián)合應(yīng)用兩種方法進(jìn)行檢測(cè),提高檢出率,避免漏診,為臨床HBV感染、復(fù)制及傳染性的判斷以及指導(dǎo)治療提供更為可靠的判定
