Passive Fecal Flotation. Passive fecal flotation is conducted by mixing fecal matter and flotation solution in a small vial to form a slurry; the vial is then filled until a positive meniscus forms (Figure 5). A cover slip is placed over the meniscus and left undisturbed for 10 minutes, which allows the eggs/cysts to float to the top (Figure 6)
