Schilddrüsen-TSH Wert Selbsttest: what can you do yourself?

A TSH self-test (e.g., from a pharmacy or via dried blood spot) can give a preliminary indication of thyroid function, but it does not replace medical diagnosis. What you can do yourself: Perform the test correctly (usually fasting in the morning), record symptoms like fatigue, weight changes, or cold sensitivity, and compare the result to the manufacturer's reference ranges. However, a single TSH value is insufficient – a full thyroid panel often requires fT3, fT4, and antibodies. If results are borderline or abnormal, you must consult a doctor. Self-medicating with thyroid hormones or iodine supplements can be dangerous (risk of over-/under-function, arrhythmias). The test is useful as a screening tool, but not diagnostic. Evidence: practice. Caveat: no specific validation data in context.
