The article examines the cause of low thyroid-stimulating hormone (TSH) level with a normal free T4 level. The decrease TSH level seen in subclinical hyperthyroidism is caused by the pituitary's response to minor elevations in serum or tissue T4 and T3 levels. In the evaluation and treatment ...
The body converts T4 to T3 in the liver and tissues by removing an iodine atom. But how many free hormones your body produces also depends on your TSH amount. For example, low T4 results in more TSH production, which then tells the thyroid gland to make more T4 and shuts off when the...
TSH levels higher than 4.5 mU/L usually indicate an underactive thyroid (hypothyroidism), and low TSH levels—below 0.4 mU/L—indicate an overactive thyroid (hyperthyroidism).1 However, there are exceptions to these interpretations and variations as to what a "normal" TSH level is. This is be...
Question 3: The TSH Puzzle Here’s an enigma which even stumped many scientists. When diagnosing for hypothyroidism (low thyroid), one of the thyroid panel tests given is for circulating TSH levels.TThe higher the TSH numbers on the test, the greater the presumed deficiency. Here is the log...

The levels of serum triiodothyronine (T3), thyroxine (T4), thyrotropin (TSH), free T3 (FT3) and free T4 (FT4) were studied in serum samples drawn in the morning. Thyroid function tests were set in relation to the severity of hepatic dysfunction and to the presence or absence of hepatic ...
Rapid reversal of subclinical hyperthyroidism in patients with large multinodular goitres after thyroidectomy. A patient is said to have subclinical hyperthyroidism if he has a depressed thyroid stimulating hormone (TSH) level but is clinically euthyroid and has a normal thyroxine (T4) and ...
Thyroid hormone serum concentrations, the thyrotropin (TSH) and prolactin (PRL) response to thyrotropin-releasing hormone (TRH) were evaluated in patients undergoing cardiopulmonary bypass (CPB) conducted in hypothermia. During CPB a marked decrease of thyroxine (T4) and triiodothyronine (T3) concentrati...
Responses of the Thyroid Gland to TSH and Other Thyroid Stimulators in the Growth-Retarded (grt) Mouse Administration of exogenous TSH to the grt mice failed to elevate the plasma T4 and triiodothyronine (T3) levels in vivo or to stimulate free T4 and ... K Kobayashi,H Yamamoto,T Kobayashi...
