What conditions can be detected by a thyroid function test?

A thyroid function test (TFT) can help detect several thyroid-related conditions, including hypothyroidism (underactive thyroid), hyperthyroidism (overactive thyroid), thyroiditis (inflammation of the thyroid gland), and Graves’ disease (an autoimmune disorder causing hyperthyroidism). TFTs can also detect thyroid hormone resistance and monitor the effectiveness of thyroid medications. Early detection of thyroid dysfunction is important to prevent complications like heart problems, weight changes, and developmental issues.
