The faecal material is mixed with the high specific gravity flotation fluid. The debris is removed with a filter and material that is less dense than the flotation fluid, such as nematode ova, will rise to the top. This can then be examined on a microscope slide. | The faecal material is mixed with the high specific gravity flotation fluid.
