Your thyroid is a gland responsible for producing essential hormones, maintaining metabolism, and regulating a number of vital bodily functions, which makes a thyroid test an important step in achieving overall health. Variances in the amount of T3 and T4 hormones produced by the thyroid can cause weakness, weight gain, depression, hair loss, and other adverse effects. Priority Lab Testing’s selection of thyroid tests evaluate your individual thyroid-produced hormone levels. We also offer affordable multi-panel thyroid testing to quickly and painlessly measure the overall health and effectiveness of your thyroid.
