welche werte bei schilddrüsenunterfunktion — what symptoms are typical?

The question about typical lab values and symptoms of hypothyroidism cannot be answered from the provided context, as it contains no thyroid-related information. Based on established medical knowledge, key laboratory markers are elevated TSH and low free T4 (fT4). In subclinical hypothyroidism, fT4 may still be normal. Common symptoms include fatigue, cold intolerance, weight gain, dry skin, constipation, brain fog, and depressed mood. Diagnosis requires a physician; self-medication with thyroid hormones is dangerous. The evidence for these statements is human-strong (clinical guidelines from the American Thyroid Association). Note: The context documents provided (DNA variants, microbiome, blood test safety, etc.) do not address thyroid function. This answer is based on general medical consensus, not on the supplied RAG material.
