What does a fecal flotation help veterinarians determine?

A fecal flotation is a diagnostic test commonly used in veterinary medicine to determine whether an animal has intestinal parasites. During this procedure, a small sample of feces is mixed with a special solution and spun in a centrifuge. The difference in specific gravity allows the eggs or cysts of parasites to rise to the surface, where they can be collected and analyzed under a microscope.

This test is particularly effective for identifying various types of parasitic infections, such as those caused by roundworms, hookworms, or Giardia. By accurately diagnosing these parasites, veterinarians can recommend appropriate treatments, effectively managing the health of the affected animal.

In contrast, other choices involve different diagnostic methods or tests. For example, testing for the presence of viruses typically requires a viral culture or other specific tests, and assessing hydration levels usually involves clinical examination or blood tests rather than fecal analysis. Similarly, identifying bacteria in the gastrointestinal tract often necessitates culture and sensitivity testing rather than a fecal flotation. Thus, the primary function of a fecal flotation test is to check for intestinal parasites, making this the correct choice.
