Final Answer:
Stool tests for Celiac disease may include fecal fat analysis and examination for fat globules. Microscopic findings may reveal villous atrophy, and relevant labs include serologic tests such as anti-tissue transglutaminase (anti-tTG) antibodies.
Step-by-step explanation:
When evaluating Celiac disease, stool tests play a role in assessing fat absorption. Fecal fat analysis involves measuring the amount of fat in the stool, and examination for fat globules can provide additional insights into malabsorption. Microscopically, the stool sample may reveal villous atrophy, a characteristic histological finding associated with Celiac disease.
In addition to stool tests, serologic tests are commonly employed. The detection of specific antibodies, such as anti-tissue transglutaminase (anti-tTG) antibodies, can aid in the diagnosis of Celiac disease. Elevated levels of these antibodies suggest an immune response to gluten, a key component in Celiac disease pathogenesis.
