The co-agglutination (Co-A) procedure was standardized and evaluated to detect hydatid antigen in fluid samples aspirated from hydatid cysts. Samples were collected from 14 hydatid cysts in different organs (liver, 7; lung, 5; multiple abdominal cysts, 1; and kidney, 1) by surgery. Echinococcus granulosus scolices and hooklets were seen in only 6 (42.85%) samples by routine microscopy. In contrast, hydatid antigen was demonstrated in all the samples by Co-A (100% sensitivity). Co-A could be employed as a simple and rapid diagnostic procedure, as an alternative to microscopy, to confirm the hydatid aetiology of a suspected cyst.
对协同凝集（Co-A）程序进行了标准化和评估，以检测从包虫囊肿抽吸的液体样本中的包虫抗原。通过手术从不同器官（肝脏，7例；肺，5例；多发性腹部囊肿，1例；肾脏，1例）的14个包虫囊肿中采集样本。通过常规显微镜检查，仅在6个（42.85%）样本中发现了细粒棘球绦虫头节和小钩。相比之下，Co-A在所有样本中均检测到包虫抗原（敏感性为100%）。Co-A可作为一种简单快速的诊断程序，替代显微镜检查，以确认疑似囊肿的包虫病因。
