What role does Zöliakie Test play in fatigue?

The provided context does not contain specific information on the role of celiac disease testing in fatigue. In general, untreated celiac disease can cause fatigue through malabsorption, chronic inflammation, and nutrient deficiencies (e.g., iron, vitamin B12, folate). A positive celiac test (IgA-tTG, endomysial antibodies, or duodenal biopsy) may therefore identify an underlying cause of fatigue. However, fatigue is a nonspecific symptom; a negative test does not rule out other causes. The evidence from the given material is unclear, as no studies or guidelines are cited. The test is well-established for diagnosis (human-strong when celiac is suspected), but for fatigue alone without other signs, its predictive value is limited. Caveat: consumer celiac tests (e.g., genetic) are not diagnostic; medical evaluation is needed.
