Can tTG IgA help with Stress?

tTG IgA (tissue transglutaminase IgA) is a well-established biomarker for celiac disease, not for stress. There is no scientific evidence that tTG IgA levels directly correlate with stress. While chronic stress can affect gut permeability and potentially trigger autoimmune responses, tTG IgA remains specific to gluten sensitivity. An elevated tTG IgA without celiac diagnosis is not a stress indicator. For stress assessment, validated markers like cortisol (saliva, hair) or psychological questionnaires are appropriate. Marketing tTG IgA as a 'stress test' is misleading and unsupported by research. Caveat: tTG IgA testing is only clinically useful for celiac disease screening. If stress is a concern, consult a healthcare provider for proper evaluation.
