When the level of Free Thyroid test at home/thyroid hormones (T3 & T4) drops too low, the pituitary gland produces Thyroid Stimulating Hormone (TSH) which stimulates the thyroid gland to produce more hormones.
Under the influence of TSH, the thyroid will manufacture and secrete T3 and T4 thereby raising their blood levels
Almost all of the T3 (and T4) found in the blood are bound to protein.
Tests can measure the amount of free T3 or the total T3 (bound plus unbound) in the blood. Most of the hormone produced by the thyroid is T4. Free Thyroid test at home
Free thyroid is a type of thyroid hormone test that measures the amount of free thyroxine (T4) and free triiodothyronine (T3) in the blood.
