Order Thyroid TestsThyroid tests measure how well the thyroid gland is functioning by quantifying the hormones it produces and the signals that regulate it. Because thyroid hormones influence metabolism, energy use, heart rate, and temperature regulation, these tests are commonly used to investigate symptoms such as fatigue, weight change, or feeling unusually cold or warm.
About Thyroid Tests in Twin Falls
Thyroid testing usually begins with a small blood sample, which is then analyzed for hormone levels and, when indicated, thyroid antibodies.
The most frequently ordered markers are thyroid-stimulating hormone (TSH), free thyroxine (T4), and free triiodothyronine (T3). TSH is released by the pituitary gland and rises when the thyroid is underactive; it falls when the thyroid is overactive. Free T4 and free T3 reflect the unbound, biologically active portions of those hormones circulating in the blood.
When autoimmune thyroid disease is suspected, antibody tests such as thyroid peroxidase (TPO) antibodies and thyroglobulin antibodies may be added. These do not measure gland function directly but can indicate an immune response directed at thyroid tissue.
Sample collection involves a standard venipuncture, typically from a vein in the arm. Results are generally available within one to three business days, though the exact timing depends on the panel ordered and the laboratory performing the analysis. Preparation is usually minimal, and any specific instructions provided by the lab should be followed.
