Because of their distinctive morphology the cysts of Giardia lamblia usually are not mistaken for cysts or eggs of other intestinal parasites. At a hospital laboratory in Kentucky a case of giardiasis was encountered in which the initial fecal examination revealed only degenerated cysts of Giardia which were mistaken for the oocysts of Isospora at the one-sporoblast stage.
由于其独特的形态，蓝氏贾第鞭毛虫的包囊通常不会被误认为是其他肠道寄生虫的包囊或虫卵。在肯塔基州的一家医院实验室，遇到了一例贾第虫病病例，其最初的粪便检查仅发现了退化的蓝氏贾第鞭毛虫包囊，这些包囊在单孢子母细胞阶段被误认为是等孢子球虫的卵囊。
