Risks and limits of TSH Männer

TSH (thyroid-stimulating hormone) is a key marker for thyroid function. In men, reference ranges typically lie between 0.4 and 4.0 mU/L, but these vary by laboratory, age, and time of day. A single TSH value from a home or consumer test is not sufficient to diagnose thyroid disease. Many factors influence TSH: stress, sleep deprivation, medications (e.g., biotin), acute illness, or even the season. A slightly elevated or decreased level may be transient and clinically irrelevant without symptoms. Consumer tests often lack free thyroid hormones (fT3, fT4) or antibodies needed for a full assessment. The evidence for interpreting TSH alone is moderate; clinical decisions require physician follow-up. Caveat: Do not self-diagnose or self-treat based on a single measurement. If abnormal, consult a doctor to rule out hyper- or hypothyroidism.
