Fecal Flotation Basic Information Definition A test to detect parasite eggs, oocysts, or cysts in feces Typical Normal Range (US units; SI units) Results are reported as positive or negative usually with a genus, species, or type (eg, strongyle) identification. Physiology Parasite eggs and cysts are concentrated in feces using a flotation solution that separates eggs/cysts from debris using the principle of buoyancy. After feces are mixed in a test tube with a flotation solution, a centrifugation step is used and the less dense parasite eggs/cysts will float at the top of the meniscus. These parasite stages are removed and examined microscopically. Because many parasite eggs and cysts will float efficiently in a solution that has a specific gravity (sg) of 1.2 to 1.3, flotation solutions, such as saturated sucrose (sg = 1.27), magnesium sulfate (sg = 1.2), or zinc sulfate (sg = 1.18), often are used. Causes of Abnormally High Levels Eggs and cysts from nematodes and protozoans inhabiting the gastrointestinal tract often will be observed.< div class='tao-gold-member'> Only gold members can continue reading.
