A thyroid test refers to a series of blood tests that assess the functioning of the thyroid gland. These tests typically include measurements of thyroid hormones such as T3 (triiodothyronine), T4 (thyroxine), and thyroid-stimulating hormone (TSH). The results help diagnose thyroid disorders like hypothyroidism or hyperthyroidism. Thyroid tests are crucial for evaluating overall thyroid function, guiding appropriate medical interventions, and ensuring hormonal balance in the body. Professional interpretation is essential for accurate assessment and informed healthcare decisions.
