随着人民生活水平的不断提高，要求吃鲜活食品的人群在增加，一些由不健康饮食习惯导致的食源性寄生虫病，如旋毛虫、囊虫、肝吸虫、并殖吸虫和刺球蚴病等呈明显上升趋势，且流行程度在加重，流行区也发生着变化。以往寄生虫病多发生在农村地区，而目前城市患者占的比重却逐年递增，如脑囊虫病、血吸虫病、肝吸虫病以及因宠物感染人体导致的弓形虫病等在城市居民中并非罕见。
寄生虫在人体肠道内寄生而引起的疾病统称为肠道寄生虫病。常见的有原虫类和蠕虫类(包括蛔虫、钩虫、蛲虫、绦虫、鞭虫、阿米巴、贾第虫、滴虫等)。肠道寄生虫的种类多，在人体内寄生过程复杂，引起的病变并不限于肠道。依据感染寄生虫的种类和部位以及人体宿主的免疫状况，临床症状和体征各异。
粪便中寄生虫卵及原虫的检查是我们常用以诊断肠道寄生虫病的方法和重要依据，它既能观察寄生虫的感染情况，考核抗寄生虫药物的疗效，也是进行这些寄生虫病流行病学调查的一种重要手段。
现有技术中的寄生虫卵检测还存在一些不足，本领域还需要研究新的寄生虫卵检测试剂盒。
