A thyroid function blood test, also known as a thyroid panel or thyroid profile, is a series of blood tests that examine the health and function of the thyroid gland.

The following are the main components of a thyroid function test:

Thyroid Stimulating Hormone (TSH): TSH is a pituitary hormone that stimulates the thyroid gland to create thyroid hormones. TSH levels that are elevated may suggest an underactive thyroid (hypothyroidism), whereas TSH levels that are low may indicate an overactive thyroid (hyperthyroidism).

Free Thyroxine (FT4): FT4 is the active form of thyroid hormone since it is not attached to proteins. It aids in the regulation of metabolism and energy production in the body.

Free triiodothyronine (FT3) is an active type of thyroid hormone that influences metabolism, energy production, and other biological activities.

Is it for me?

The thyroid function blood test is used for a variety of applications, including:

Thyroid Disorders Diagnosis: The test aids in the diagnosis of hypothyroidism (underactive thyroid) and hyperthyroidism (overactive thyroid), as well as autoimmune thyroid disorders.

Individuals with thyroid issues are frequently examined through regular thyroid function testing to ensure that hormone levels are within the recommended range.

Thyroid function tests are performed as part of the evaluation procedure for thyroid nodules, which are growths in the thyroid gland.
