A collection of reagents and other associated materials (e.g., filters, containers) intended to be used for the isolation and concentration of intestinal parasites [e.g., helminth eggs and larvae, protozoan trophozoites and cysts] from a faecal specimen, using one or a combination of techniques (e.g., centrifugation, filtration, organic solvent or surfactant treatment), for further in vitro diagnostic investigation. This is a single-use device.
