Abstract:

Objective To evaluate the effect of gold labeling immunoassay(GLIA)on field screening for Toxoplasma gondii infection of blood donors. Methods A total of 1 056 specimens from the blood donors were examined by using GLIA and ELISA. Results The Toxoplasma IgG positive rates of GLIA and ELISA were 5.46%(49/898),and 4.90%(44/898),respectively,and there was no significant difference( χ2 = 0.610,P > 0.05) . Those with positive results in both the two methods accounted for 4.45%(40/898),and those with negative results in both the two medhods accounted for 94.1%(845/898) . The corresponding rate was 98.6%(885/898) . Kappa index was 0.843,and the detection results of the two methods were consistent. Conclusion The de? tection efficiency of GLIA is proved to be of good agreement with ELISA,and GLIA has superior features,including easy imple? mentation and quick efficiency, so it could be used for field screening for Toxoplasma gondii infection of blood donors.

摘要:

目的 观察评价金标法用于献血员弓形虫感染现场筛查的效果。 方法 收集ALT、 HBV、 抗?HCV、 抗?HIV和抗? TP均为阴性的献血员血液, 经抗凝离心后分离出血浆, 采用金标法与ELISA法平行检测血浆中弓形虫IgG阳性率, 分析、 评价检测效果。 结果 金标法与ELISA法检测弓形虫IgG阳性率分别为5.46% (49/898) 和4.90% (44/898), 2种方法的阳性检出率间差异无统计学意义 (χ2 =0.610, P>0.05); 检测结果同为阳性者占4.45% (40/898), 同为阴性者占94.1% (845/898),总符合率为98.6% (885/898); Kappa值为0.843, 2种方法检测献血员的结果一致。 结论 金标法检测献血员血浆中弓形虫 IgG抗体符合率高, 且具有操作简单快速等优点, 可用于献血员的现场筛查。
