The thyroid gland, a small butterfly-shaped gland at the front of the neck, is one of the most important endocrine glands. It regulates many vital processes, such as metabolism, energy production rate, growth, and development. The thyroid produces two main hormones, T3 and T4, while their production is regulated by the Thyroid-Stimulating Hormone (TSH). The Thyroid Check-up Panel helps to accurately assess the function of this vital gland and detect any disorders early.
