Adults 0.4 to 4.0 µIU/mL. This is a commonly used laboratory range; confirm it with the lab, because ranges vary by method.
No. None narrower than the laboratory's range is widely agreed, so the page shows the laboratory range only.
TSH reacts to small changes in thyroid hormone, so it is usually the first thyroid test. A high TSH often points to a slow thyroid; a low TSH to an overactive one.
Time of day, illness, pregnancy and some medicines. Biotin supplements can interfere with the test itself, so tell us if you take them.
