Blastocystis hominis cysts in faeces can be concentrated on Ficoll column. They are pleomorphic in shape having a mean diameter of 6.65 microns (S.D. = 2.32). They may or may not have a membranous layer surrounding them. The membranous layer tends to come off with pressure or dying of the specimen and corresponds to the fibrillar layer observed under the electron microscope. The Ficoll concentration technique is also useful for concentrating other protozoan cysts.
粪便中的人芽囊原虫包囊可通过Ficoll柱进行浓缩。它们形状多样，平均直径为6.65微米（标准差=2.32）。它们可能有也可能没有围绕它们的膜层。膜层在施加压力或标本死亡时往往会脱落，这与在电子显微镜下观察到的纤维层相对应。Ficoll浓缩技术对浓缩其他原生动物包囊也很有用。
