About Thyroid Tests in Walnut
Thyroid testing refers to a group of blood tests that assess the thyroid gland, a small butterfly-shaped organ in the neck that influences metabolism, heart rate, and body temperature.
The most frequently ordered marker is thyroid-stimulating hormone, or TSH, which is released by the pituitary gland and tells the thyroid how much hormone to produce. Because TSH responds to thyroid hormone levels, it is often used as a first-line screening tool.
Additional markers include free thyroxine (free T4) and free triiodothyronine (free T3), the two primary hormones the thyroid secretes. In some cases, tests for thyroid antibodies are added to detect autoimmune activity directed at the gland.
Samples are collected through a standard blood draw from a vein, typically in the arm. Results are generally available within one to three business days, and preparation instructions should be followed as provided by the laboratory performing the collection.
