What is one of the fecal tests performed in lab?

Fecal centrifugation is a valid and commonly performed laboratory test used to analyze fecal samples. This process involves spinning the feces at high speeds to separate solid particles from liquids. Through centrifugation, clinicians can obtain a clearer sample that allows for the examination of parasites, eggs, or other stool components that may not be easily visible in a non-centrifuged sample. This technique enhances the accuracy of diagnostic tests performed on the fecal matter, making it a crucial step in many veterinary and medical laboratory protocols.

The other options, while relevant to fecal diagnostics, are either less commonly performed or represent specific tests rather than general laboratory procedures that are routinely employed.
