摘要
为研制鼠疫耶尔森菌F1抗体检测试剂国家参考品,本研究制备了6份F1抗体阳性参考品、8份F1抗体阴性参考品、1份最低检出限参考品和1份重复性参考品,组成了鼠疫耶尔森菌F1抗体检测试剂国家参考品。对参考品进行均匀性检查及稳定性评估,并组织4家实验室进行协作标定。结果显示,参考品均匀性及稳定性良好。协作标定结果显示,6份阳性参考品阳性率均为100%;8份阴性参考品阴性率均为100%;最低检出限参考品的检出水平介于1~100倍稀释度;重复性参考品检测结果一致(其中酶联免疫法及上转发光法试剂检测结果的变异系数均小于15%)。结果表明,本研究建立的鼠疫耶尔森菌F1抗体检测试剂国家参考品基本符合体外诊断试剂参考品的要求,可用于相关试剂的质量评价。
The present paper aims to prepare a national reference for detection reagents for Yersinia pestis F1 antibody,which was consisted of six positive references,eight negative references,one minimum detection limit reference and one repetitive reference.The uniformity and stability of this reference met the requirements for national references.The collaborative calibration results of four laboratories showed that six positive references were 100%positive,eight negative references were 100%negative,the detection level of the minimum detection limit reference was 1-100 times dilution,and the testing results of repetitive reference were consistent(for the detection reagents based on enzyme-linked immunosorbent assay and up-converting phosphor technology,the coefficient of variation of testing results was less than 15%).So a national reference for detection reagents for Yersinia pestis F1 antibody was prepared which was suitable for the quality evaluation and control of related reagents.
