本文用酶联免疫吸附法(ELISA)对105例青霉素敏过及对照组病人进行了青霉素特异IgE抗体检测。由于采用“固相免疫吸附法”去除封闭抗体IgG干扰,提高了阳性率,阳性符合率为75.29％,阴性符合率为80％,总符合率为76.19％,除去可疑者为90.91％。过敏组与对照组差异有显著性(P<0.001),故认为本方法特异、灵敏、安全。 In this study, 105 patients with penicillin-sensitive and control group were tested for penicillin-specific IgE by enzyme-linked immunosorbent assay (ELISA). The positive rate was 75.29%, the negative coincidence rate was 80%, the total coincidence rate was 76.19%, and the suspicious person was removed as 90.91% because of adopting “solid phase immunoadsorption method” to remove the blocking antibody IgG. The difference between the allergy group and the control group was significant (P <0.001), so that the method is specific, sensitive and safe.
