Is tTG IgA useful for Wechseljahre?

The question of whether tTG-IgA is useful for menopause cannot be answered with scientific evidence from the provided context. tTG-IgA (tissue transglutaminase antibodies) is a well-established biomarker for diagnosing celiac disease, an autoimmune condition affecting the small intestine. There are no studies or guidelines supporting its direct utility for menopause. While undiagnosed celiac disease can exacerbate symptoms like fatigue, bone loss, or nutrient deficiencies during perimenopause, the test is not a menopause test. Marketing tTG-IgA as a 'hormone' or 'menopause' test would be misleading and lacks evidence. If a patient presents symptoms suggestive of celiac disease (e.g., chronic diarrhea, bloating, iron deficiency), the test is appropriate—but not specific to menopause. For evaluating hormonal status or menopausal symptoms, markers like FSH, estradiol, or AMH are indicated. The evidence for using tTG-IgA in menopause is therefore rated as 'marketing/unclear' because no validated data from the provided context exist. Caution is warranted: consumer tests offering tTG-IgA without medical indication may lead to misinterpretation and unnecessary anxiety.
