摘 要: | 目的采用时间分辨荧光免疫分析法(TRFIA)建立高灵敏的抗弓形虫(TOX)IgM抗体的检测方法。方法采用二抗间接法建立抗TOX IgM抗体的TRFIA。结果方法的批内和批间变异系数(CV)分别为1.9%和3.8%,敏感性为0.4 U/mL,可测范围为0.4~200 U/mL,20%、50%和80%的有效剂量(ED20、ED50和ED80)分别为36.3、88.2和147.8 U/mL。检测健康体检人员的血清,标本的测定值为(5.3±2.3)U/mL,建议阳性阈值为10 U/mL。结论抗TOX IgM抗体的TRFIA敏感性高、稳定性好,在优生优育及器官移植上具有很好的应用前景。

Abstract: | Objective To develop a time-resolved fluoroimmunoassay(TRFIA) with high sensitivity for the detection of anti-Toxoplasma(TOX)-IgM antibody.Methods The tested specimen or reference standard was added to micro-titer plate coated with the TOX antigen and the europium-labelled anti human IgM antibody was added.Results The between-run and within-run coefficients of variation(CV) of this TRFIA were 1.9% and 3.8% respectively.The sensitivity was 0.4 U/mL.The range of testing was from 0.4 to 200 U/mL.The TRFIA prov... |
