Order Thyroid TestsThyroid testing evaluates how well the thyroid gland is functioning by measuring specific hormones and related markers in the blood. Because thyroid hormones influence metabolism, energy regulation, and organ function throughout the body, these tests are used to investigate symptoms such as fatigue, weight changes, and temperature sensitivity, as well as to monitor known thyroid conditions.
About Thyroid Tests in Irvine
Thyroid testing centers on hormones produced by the thyroid and the pituitary signal that regulates them.
The thyroid produces thyroxine (T4) and triiodothyronine (T3), hormones that help set the body's metabolic rate. Most T4 circulates bound to carrier proteins, so tests often measure free T4 and free T3 to assess the unbound, active fraction.
Thyroid-stimulating hormone (TSH) is released by the pituitary gland and tells the thyroid how much hormone to produce. Because TSH responds sensitively to small changes in thyroid hormone levels, it is frequently the first marker ordered when thyroid dysfunction is suspected.
Some panels also include thyroid antibodies, such as thyroid peroxidase (TPO) antibodies, which can indicate an autoimmune contribution to thyroid disease. Results are interpreted together, since a single marker rarely tells the full story.
