The thyroid gland is a small butterfly-shaped gland in the front of the neck which uses iodine to produce hormones which control your metabolism. These hormones regulate the speed at which your brain, heart, muscles and liver work. Every cell in the body depends on thyroid hormones to produce energy. Your thyroid is intricately connected with every system in your body, so if a thyroid test reveals it’s not working properly you most likely won’t feel great. Thyroid disorders typically present later in life, and if you're a woman over 35 your odds of an abnormal thyroid test result increase significantly.
Your thyroid gland produces hormones that regulate growth and energy expenditure. Thyroid disorders are quite common, and many people don’t have any symptoms at all. This thyroid test screens for the thyroid hormones that play a key role in regulating the body’s metabolism.
