目的:探讨多参数室内质控方法在实时荧光定量PCR检测乙型肝炎病毒核酸(HBV -DNA )的意义。方法:以实时荧光定量PCR法检测HBV -DNA ,统计分析我院2012年10月至12月阳性质控品检测结果的对数值、标准曲线的斜率、截距、相关系数(r ),以及系列标准品扩增Ct值的均值(X )、标准差(s )和变异系数(cv );并以各参数结果在±3s内作为室内质控在控判断。结果:当只用阳性质控品检测结果对数值超过±3s作为质控失控判断时,本文观察时间段有两次结果失控;如以斜率、截距、相关系数和标准品扩增Ct值超过±3s作为室内质控失控判断时,这两次结果都未失控。按阳性质控品失控规则对失控的两次标本进行重新检测后前后结果都一致,说明阳性质控品结果失控是偶然误差造成,当斜率、截距、相关系数和标准品扩增Ct值都未失控时,仅有某个水平阳性质控品失控可考虑是偶然原因。结论:实时荧光定量 PCR检测HBV -DNA的室内质控中,用阳性质控品检测结果的对数值,结合标准曲线的斜率、截距和相关系数,以及标准品扩增的Ct值作为室内质控的监测手段,可为HBV -DNA检测提供更可靠的结果保证。
目的:探討多參數室內質控方法在實時熒光定量PCR檢測乙型肝炎病毒覈痠(HBV -DNA )的意義。方法:以實時熒光定量PCR法檢測HBV -DNA ,統計分析我院2012年10月至12月暘性質控品檢測結果的對數值、標準麯線的斜率、截距、相關繫數(r ),以及繫列標準品擴增Ct值的均值(X )、標準差(s )和變異繫數(cv );併以各參數結果在±3s內作為室內質控在控判斷。結果:噹隻用暘性質控品檢測結果對數值超過±3s作為質控失控判斷時,本文觀察時間段有兩次結果失控;如以斜率、截距、相關繫數和標準品擴增Ct值超過±3s作為室內質控失控判斷時,這兩次結果都未失控。按暘性質控品失控規則對失控的兩次標本進行重新檢測後前後結果都一緻,說明暘性質控品結果失控是偶然誤差造成,噹斜率、截距、相關繫數和標準品擴增Ct值都未失控時,僅有某箇水平暘性質控品失控可攷慮是偶然原因。結論:實時熒光定量 PCR檢測HBV -DNA的室內質控中,用暘性質控品檢測結果的對數值,結閤標準麯線的斜率、截距和相關繫數,以及標準品擴增的Ct值作為室內質控的鑑測手段,可為HBV -DNA檢測提供更可靠的結果保證。

to evaluate the significance of the application of multi -parameters in the internal quality control of detection of HBV -DNA by real -time quantitative PCR .Methods :statistic analysis was conducted by the relative parameters from Octmber to December in 2012 :the logarithm of HBV - DNA concentration of the positive control ,the cycle threhold value of the standard samples and the slope ,intercept and correlation coefficient of the corresponding standard curves ,SD and CV of these parameters were calculated .The results of the positive control that run out of X ± 3s were suppossed to be out of control . Results :there were two results out of control during theses two months simply according to the logarithm of HBV -DNA concentration of the positive control . However ,these two analytical runs were in control according to the relative parameters of standard samples and curves .Since the redetection of these two analytcial runs found the consistency of the results ,accidental error may be blamed for these loss of control .Conclusion :the application of multi -parameters in the internal quality control of the detection of HBV -DNA by real -time quantitative PCR may contribute to the quality assureance .
