Description
T4 is a specialized diagnostic test designed to evaluate thyroid function and detect autoimmune-related conditions. It measures the levels of thyroxine (T4), a crucial hormone produced by the thyroid gland that regulates metabolism, energy, and overall body balance. This test plays a vital role in identifying thyroid disorders such as hypothyroidism, hyperthyroidism, and autoimmune diseases like Hashimoto’s thyroiditis or Graves’ disease.
