Thyroid Hormones
T3,T4, and calcitonin
TSH from the controls the release of thyroid hormone
Anterior Pituitary Gland
T3 is more what compared to T4
More potent
Thyroid Diagnostic Tests
TSH
Serum free T4
T3 and T4
T4 Resin Uptake
Thyroid Antibodies
Radioactive Iodine Uptake
FIne Needle Biopsy
Thyroid Scan, radioscan, scintiscan
Serum thyroglobulin

Determines location, size and shape and function of thyroid
Severely stunted physical and mental growth owing to untreated congenital deficiency of thyroid
