摘要: 目的 尝试制备以胎牛血清(FCS)替代人血清为基质的乙型肝炎病毒(HBV)标志物室间质评样本。方法 以FCS作为基质稀释人血清HBV标志物高值样本制备室间质评样本,并对制备样本进行基质效应和互换性实验、均匀性和稳定性评估及初步临床应用。结果 使用两种检测方法 验证制备样本的可互换性,检测值分布于95%可信区间内,相关性很好。雅培i1000全自动免疫分析仪检测HBV 5个项目[乙型肝炎病毒表面抗原(HBsAg)、乙型肝炎病毒表面抗体(HBsAb)、乙型肝炎病毒e抗原(HBeAg)、乙型肝炎病毒e抗体(HBeAb)、乙型肝炎病毒核心抗体(HBcAb)]制备物结果的F值均<F界值(F界值=3.02),保存于-20 ℃和4 ℃时可稳定1个月以上。20家使用化学发光法[ABBOTT i2000全自动免疫分析仪(简称ABBOTT i2000)]和20家使用酶免法(科华试剂)的实验室HBsAg、HBsAb、HBeAg、HBeAb、HBcAb的变异系数(CV)分别为ABBOTT i2000仪器组7.60%、7.79%、6.37%、13.30%、3.61%,科华试剂组11.67%、14.72%、9.11%、12.30%、9.75%。结论 通过试验验证以FCS为基质制备的质评样本的互换性、稳定性和均匀性满足室间质评样本要求,初步认为FCS在一定程度上可以作为基质用于HBV标志物室间质评样本的制备。

Abstract: Objective To try to use fetal calf serum (FCS) to prepare hepatitis B virus (HBV) marker external quality assessment material instead of human serum. Methods FCS was used as matrix, and human serum high-level HBV marker external quality assessment material was diluted. The matrix efficiency, interchangeability, homogeneity, stability and clinical application significance were evaluated. Resutls For the interchangeability of the 2 determination methods, the results were within 95% confidence interval, and the correlation was good. F values were all <cut-off value of F (3.02) by Abbott i1000 for 5 HBV parameters [hepatitis B surface antigen (HBsAg), anti-hepatitis B surface antigen antibody (HBsAb), hepatitis B e antigen (HBeAg), anti-hepatitis B e antigen antibody (HBeAb) and anti-hepatitis B core antigen antibody (HBcAb)]. The stability was good above 1 month when storing under -20℃ and 4 ℃. The coefficients of variation (CV) for HBsAg, HBsAb, HBeAg, HBeAb and HBcAb were 7.60%, 7.79%, 6.37%, 13.30% and 3.61% by 20 laboratories using Abbott i2000, and were 11.67%, 14.72%, 9.11%, 12.30% and 9.75% by 20 laboratories using KHB reagents. Conclusions When using FCS as matrix, the interchangeability, homogeneity and stability meet the requirements of external quality assessment, and FCS can be used as matrix for the preparation of HBV marker external quality assessment material primarily.
