What is the purpose of a fecal flotation test?

The purpose of a fecal flotation test is primarily to diagnose the presence of intestinal parasites. This diagnostic tool is essential in veterinary medicine because it allows technicians and veterinarians to identify the eggs or oocysts of parasites that may be present in the gastrointestinal tract of animals. During the test, a small sample of feces is mixed with a special solution that has a specific gravity lower than that of the parasite eggs. As the solution is mixed and allowed to sit, the eggs float to the surface, forming a layer of floating debris that can then be examined under a microscope. This method is particularly effective for detecting common parasites such as roundworms, hookworms, and protozoa.

The other options do not pertain to the objectives of a fecal flotation test. Measuring dehydration levels is typically accomplished through physical examinations, blood tests, or other clinical assessments. Assessing kidney function involves testing blood urea nitrogen (BUN) and creatinine levels, which is unrelated to fecal analysis. Evaluating heart health generally requires different diagnostic approaches such as echocardiography or electrocardiograms, rather than examining fecal matter.
