Why you should order a Thyroid test online.
A Thyroid test includes T3, T4, and TSH in the body. Linked to molecules, T3 and T4 in the blood is synced to protein molecules. The unbound T3 and T4 represents the bodys thyroid levels. Thyroid levels represent active hormone present to act with receptors of cells in ones body.
Below normal are thyroid levels in hypothyroidism. A lot of TSH is excreted by the pituitary thus increasing the TSH thyroid levels. A Thyroid test is performed when blood TSH thyroid levels are low, often kept down to levlels below 0.01 mIU per L, hyperthyroidism occurs. Due to a six week blood to test result period, thyroid function or abnormal thyroid hormone levels may appear normal. For this reason, a FT4 and FT3 determination must be ran.
T3 is only produced in small amounts by the thyroid gland. In the liver, the majority of T3 present in the blood is made by conversion of T4 to T3.
