About Thyroid Tests in Fresno
Thyroid Tests typically assess one or more hormones produced by the thyroid gland and the pituitary gland's regulatory signal.
The thyroid gland produces thyroxine (T4) and triiodothyronine (T3). Much of the T4 and T3 in circulation is bound to carrier proteins, while a smaller fraction remains free and biologically active. Laboratory testing can measure total hormone levels or the free fractions.
Thyroid-stimulating hormone (TSH) is produced by the pituitary gland and signals the thyroid to release its hormones. Because TSH responds to circulating thyroid hormone levels, it is often used as a first-line marker of thyroid function.
Some panels also include thyroid antibodies, which are proteins the immune system may produce against thyroid tissue. Antibody testing can provide additional context when thyroid function is abnormal, but it is not part of every thyroid panel.
