Thyroid Tests

A thyroid panel test is a blood test that measures the levels of thyroid hormones and thyroid-stimulating hormone (TSH) in the body.

• It typically includes the measurement of thyroid hormones T3 (triiodothyronine) and T4 (thyroxine), as well as TSH, which is produced by the pituitary gland and regulates thyroid hormone production.
• The test helps evaluate thyroid function and diagnose conditions such as hypothyroidism (underactive thyroid) or hyperthyroidism (overactive thyroid).

A thyroid antibodies test is a blood test that measures the levels of specific antibodies associated with thyroid disorders.

• The test primarily checks for the presence of thyroid autoantibodies, such as thyroid peroxidase antibodies (TPO antibodies) and thyroglobulin antibodies (TG antibodies).
• These antibodies are often found in autoimmune thyroid conditions like Hashimoto's thyroiditis and Graves' disease.

A TSH (thyroid-stimulating hormone) test is a blood test that measures the level of TSH in the bloodstream.

• TSH Test is produced by the pituitary gland and plays a key role in regulating the thyroid gland's production of thyroid hormones (T3 and T4).
• TSH test helps evaluate thyroid function and diagnose conditions such as hypothyroidism (underactive thyroid) or hyperthyroidism (overactive thyroid).

Both TSH (thyroid-stimulating hormone) and T4 (thyroxine) are essential components in assessing thyroid function. TSH is produced by the pituitary gland and regulates the production of T4 by the thyroid gland. TSH is typically considered the most sensitive marker for thyroid function and isoften used as the initial screening test. It helps determine whether the thyroid gland is functioning properly. T4, on the other hand, is the primary hormone produced by the thyroid gland and plays a crucial role in regulating metabolism in the body.

When T3 (triiodothyronine) levels are high, it can indicate an overactive thyroid or hyperthyroidism. High T3 levels may cause symptoms such as weight loss, rapid heartbeat, irritability, restlessness, and heat intolerance. Hyperthyroidism can be caused by conditions like Graves' disease, thyroid nodules, or thyroiditis. Treatment options may include antithyroid medications, radioactive iodine therapy, or thyroid surgery, depending on the underlying cause. It's important to consult with a healthcare professional for a comprehensive evaluation and appropriate management of high T3 levels.

The Calcitonin Test is a diagnostic tool used to measure the levels of calcitonin, a hormone produced by the C cells in the thyroid gland. This test is primarily employed to detect and monitor medullary thyroid cancer (MTC), a rare form of thyroid cancer that arises from these specific cells. Calcitonin levels are typically elevated in individuals with MTC, and the test helps in the early detection, diagnosis, and management of the disease. Additionally, the test may be used to evaluate individuals with a family history of MTC or those with thyroid nodules.

A Thyroglobulin Test is a blood test that measures the level of thyroglobulin, a protein produced by the thyroid gland. This test is primarily used to monitor patients with thyroid cancer.

The normal ionized calcium level in blood is approximately 4.65 to 5.28 mg/dL.
