About Thyroid Tests in Chicago
Thyroid Tests typically measure thyroid-stimulating hormone (TSH) and may include free thyroxine (T4) and free triiodothyronine (T3), depending on the panel ordered.
TSH is produced by the pituitary gland and signals the thyroid to release T4 and T3. Because TSH responds to circulating thyroid hormone levels, it is often the first marker reviewed when thyroid function is in question.
Free T4 and free T3 reflect the unbound, biologically active portions of these hormones. Results are interpreted together, since an abnormal TSH with normal free hormone levels can indicate subclinical dysfunction.
Some panels also include thyroid peroxidase (TPO) antibodies or thyroglobulin antibodies to assess autoimmune contributions. Preparation is generally minimal, and the sample is collected through a standard blood draw.
