2. Thyroid function tests - Wikipedia

   en.wikipedia.org/wiki/Thyroid_function_tests

   However, when TSH is measured by itself, it can yield misleading results, so additional thyroid function tests must be compared with the result of this test for accurate diagnosis. [4] [5] [6] TSH is produced in the pituitary gland. The production of TSH is controlled by thyrotropin-releasing hormone (TRH), which is produced in the hypothalamus ...

3. TRH stimulation test - Wikipedia

   en.wikipedia.org/wiki/TRH_stimulation_test

   Prior to the availability of sensitive TSH assays, thyrotropin releasing hormone or TRH stimulation tests were relied upon for confirming and assessing the degree of suppression in suspected hyperthyroidism. Typically, this stimulation test involves determining basal TSH levels and levels 15 to 30 minutes after an intravenous bolus of TRH ...

4. Thyroid-stimulating hormone - Wikipedia

   en.wikipedia.org/wiki/Thyroid-stimulating_hormone

   TSH concentrations are measured as part of a thyroid function test in patients suspected of having an excess (hyperthyroidism) or deficiency (hypothyroidism) of thyroid hormones. Interpretation of the results depends on both the TSH and T 4 concentrations. In some situations measurement of T 3 may also be useful.

5. Jostel's TSH index - Wikipedia

   en.wikipedia.org/wiki/Jostel's_TSH_index

   Jostel's TSH index (TSHI or JTI), also referred to as Jostel's thyrotropin index or Thyroid Function index (TFI), is a method for estimating the thyrotropic (i.e. thyroid stimulating) function of the anterior pituitary lobe in a quantitative way. [1] [2] The equation has been derived from the logarithmic standard model of thyroid homeostasis.

6. Thyroid - Wikipedia

   en.wikipedia.org/wiki/Thyroid

   Thyroid function tests include a battery of blood tests, including the measurement of the thyroid hormones, as well as the measurement of thyroid stimulating hormone (TSH). [84] They may reveal hyperthyroidism (high T 3 and T 4), hypothyroidism (low T 3, T 4), or subclinical hyperthyroidism (normal T 3 and T 4 with a low TSH). [84]

   Thyroid stimulating hormone (TSH) is produced by the pituitary gland, another hormone-producing organ in the head. This in turn causes the thyroid to produce T3 and T4, which play a role in the ...
