脑囊虫病是一种严重危害人体健康的常见寄生虫病。早期诊断、早期治疗具有重要临床意义。目前常采用免疫学方法检测囊虫特异性循环抗体（CAb）及循环抗原（CAg）与CT检查联合诊断脑囊虫病。免疫学方法简单、取材方便、交叉反应较少，有较高的敏感性和特异性，已广泛应用于寄生 Cysticercosis is a common parasitic disease that seriously affects human health. Early diagnosis, early treatment has important clinical significance. Immunocytochemistry is currently used to detect cysticercosis-specific circulating antibodies (CAb) and circulating antigen (CAg) combined with CT examination of cerebral cysticercosis. Immunological method is simple, convenient access, less cross-reaction, high sensitivity and specificity, has been widely used in parasitic
