Thyroxine-binding globulin (TBG) is a globulin protein that in humans is encoded by the SERPINA7 gene.TBG binds thyroid hormones in circulation.It is one of three transport proteins (along with transthyretin and serum albumin) responsible for carrying the thyroid hormones thyroxine (T 4) and triiodothyronine (T 3) in the bloodstream.
The therapeutic target range TSH level for patients on treatment ranges between 0.3 and 3.0 μIU/mL. [18] For hypothyroid patients on thyroxine, measurement of TSH alone is generally considered sufficient. An increase in TSH above the normal range indicates under-replacement or poor compliance with therapy.
An operating temperature is the allowable temperature range of the local ambient environment at which an electrical or mechanical device operates. The device will operate effectively within a specified temperature range which varies based on the device function and application context, and ranges from the minimum operating temperature to the maximum operating temperature (or peak operating ...
The half-life of T 3 is about 2.5 days. [3] The half-life of T 4 is about 6.5 days. [4] T 3 levels start to rise 45 minutes after administration and peak at about 2.5 hours. Although manufacturer of Cytomel states half-life to be 2.5 days the half-life variability is great and can vary depending on the thyroid status of the patient.
T4 temper 6061 has an ultimate tensile strength of at least 180 MPa (26 ksi) [8] or 210 MPa (30 ksi) [7] and yield strength of at least 110 MPa (16 ksi). It has elongation of 10-16%. It has elongation of 10-16%.
Half-life elimination is 6–7 days for people with normal lab results; 9–10 days for people with hypothyroidism; 3–4 days for people with hyperthyroidism. [18] Thyroid hormones are primarily eliminated by the kidneys (about 80%), with urinary excretion decreasing with age. [18] The remaining 20% of T 4 is eliminated in the stool. [18]
An elevation in thyroid hormone levels is suggestive of thyroid storm when accompanied by signs of severe hyperthyroidism but is not diagnostic as it may also correlate with uncomplicated hyperthyroidism. [15] [18] Moreover, serum T3 may be normal in critically ill patients due to decreased conversion of T4 to T3. [15]
After long-term heavy strain, levels of thyroid hormones decrease. [2] This is exacerbated by other stressors such as undernutrition and lack of sleep, such as in a military training setting. During endurance exercise, before exhaustion, elevated thyroid hormone levels may happen due to increased expected energy demand (type 2 allostatic load). [2]
