Thyroid is a small gland in the lower-front part of the neck. It is responsible for the regulation of many of the body?s processes, such as metabolism, energy generation, and mood. Thyroid tests are a series of blood tests such as T3, T3RU, T4, and TSH used to check the function of the thyroid. The growth of the Global Thyroid Test Market is driven by various factors such as an increase in the prevalence of thyroid disorders, increasing prevalence of lifestyle diseases, and increasing mergers & acquisitions by prominent players in the market. However, lack of knowledge about the symptoms and causes of the thyroid is projected to hamper the growth of the global thyroid test market.
