用羊源棘球蚴囊液，原头节及生发层抗原对94例包虫病患者者、44例非包虫病患者及50例健康人血清进行了酶联A蛋白斑点免疫吸附试验。其结果显示：囊液、原头节、生发层抗原的敏感性分别为94．7％、95．7％和96．8％；特异性为81．9％、92．6％和92．6％。生发层及原头节抗原特异性高于囊液抗原。 94 cases of echinococcosis patients, 44 cases of non-hydatid disease patients and 50 healthy human serum were tested for enzyme-linked immunosorbent assay (ELISA) with dot immunosorbent assay. The results showed that the sensitivity of cyst fluid, procambium and germinal layer antigen were 94.7%, 95.7% and 96.8% respectively; the specificity was 81.9%, 92.6% and 92.6 %. Germinal layer and protoscoleces antigen specificity than cystic fluid antigen.
