Normal tsh and reduced t4
WebThyroid function tests are used to check for thyroid problems. The tests measure the amount of thyroid stimulating hormone (TSH), thyroxine (T4), and triiodothyronine (T3) in your blood. The pituitary gland in your brain makes TSH and sends it to your thyroid gland. TSH controls the production of thyroid hormones. WebFurosemide competes for T4-binding sites on TBG, prealbumin, and albumin, so that a single high dose can acutely lower the total T4 level. Phenytoin and carbamazepine reduce serum protein binding of levothyroxine, and total and free T4 may be reduced by 20% to 40%, but most patients have normal serum TSH levels and are clinically euthyroid.
