Evaluation of a Flotation Adapted Parasep® for Stool Ova and Parasite Examination

Stool ova and parasite examination using concentration methods remains the gold standard for the investigation of digestive parasitosis. Recently, single-use filtration devices have been marketed for stool concentration sedimentation methods such as MIF or Bailenger, which improve the analytical quality by avoiding contact with feces. In this study, the Parasep® device was adapted to the Faust technique flotation method. In addition, the performance between conventional techniques (MIF concentration and Faust) and techniques using this device was evaluated on 25 formalin-preserved stools and 3 fresh stools. With the Parasep device, the main parasites (protozoa or helminths) were isolated, and the technical requirements such as hygiene control for the operator and realization according to good laboratory practice were improved due to the filtration device.
