摘要: 目的评价人工合成三糖抗原在结核病血清诊断的应用前景?方法用人工合成的结核杆菌酚糖酯三糖抗原Tb NT P BSA(naturaltrisaccharide phenylpropionate bovineserumalbumin)作抗原,用ELISA法检测了40例结核患者,52个健康对照的血清标本?结果本方法的特异性?敏感性分别为:检测抗Tb NT P BSAIgG抗体时为94.2%和20.0%;检测抗Tb NT P BSAIgM抗体时为79.6%和45.0%?结论该抗原的特异性?敏感性似不理想,有待进一步改进。

Abstract: Objective To evaluate of Tb NT P BSA antigen in the diagnosis of tuberculosis.Method Sera from 40 tuberculosis cases and 52 healthy controls were assayed by ELISA using Tb NT P BSA(containing the terminal triglycosyl unit of the M.tuberculosis phenolic glycolipid) as antigen.Results The sensitivity and specificity were 94.2%,20.0% for IgG and 79.6%,45.0% for IgM antibody activity respectively.Conclusion This antigen is not sensitive,that will limit its use in the serodiagnosis of tuberculosis.
