Thyroid levels can be checked through blood tests or imaging tests. Blood tests, such as thyroid-stimulating hormone (TSH) and free thyroxine (T4), can measure the levels of thyroid hormones in the blood. Imaging tests, such as thyroid scans and ultrasounds, can provide images of the thyroid gland to assess its size, shape, and structure.
Regular thyroid level checks are important for maintaining overall health and well-being. Thyroid hormones play a crucial role in metabolism, growth, and development, and imbalances in these hormones can lead to a range of health problems.
