The Thyroid basic Panel with TSH includes several common tests which evaluate Thyroid function and can aid in the diagnosis of thyroid disorders. This panel includes Thyroid Stimulating Hormone (TSH), Thyroxine (T4), T3 Uptake, Free Thyroxine (T4) Index.
Thyroid Stimulating Hormone (TSH) is produced by the pituitary gland and aids the thyroid gland in producing T4 and T3.
T4 is a hormone produced by the thyroid gland which helps maintain the body's metabolism as well as other systems and functions.
T3 Uptake helps evaluate the amount of proteins in the blood which carry thyroid hormones throughout the body.
Free Thyroxine (T4) Index is a comparison of the amount of T4 which is unbound or free to that which is bound to proteins in the blood.
This test is commonly ordered as a regular screening for healthy thyroid function or when someone is experiencing symptoms associated with thyroid disorders.
