Advanced Thyroid Check
In addition to screening for the thyroid hormones that play a key role in regulating metabolism, this advanced thyroid function blood test detects the presence of and measures the quantity of specific thyroid autoantibodies to determine whether autoimmune disease may be impacting thyroid function.
This thyroid antibodies test includes:
Thyroid peroxidase antibodies work against thyroid peroxidase, an enzyme that plays a part in the T4-to-T3 conversion and synthesis process. TPO antibodies can be evidence of tissue destruction, such as Hashimoto's disease.
When your immune system attacks the thyroid it often targets thyroglobulin which causes it to produce antithyroglobulin antibodies. Thyroglobulin antibodies are positive in about 60% of Hashimoto’s patients and 30% of Graves patients.
Your thyroid gland produces hormones that regulate growth and energy expenditure. Thyroid disorders are quite common, and many people don’t have any symptoms at all. This thyroid test screens for the thyroid hormones that play a key role in regulating the body’s metabolism.
This thyroid test measures:
Communicates with the thyroid gland to produce T3 and T4 which regulate metabolic functions. High TSH thyroid test levels indicates an underactive thyroid, and low levels an overactive thyroid.
Measures the thyroxine that is freely circulating and able to regulate metabolism. High FT4 thyroid test levels indicate an overactive thyroid, and low levels an underactive thyroid.
Measures the triiodothyronine that is freely circulating. High FT3 thyroid test levels indicate an overactive thyroid, and low levels an underactive thyroid.
