TSI Test: Detecting Graves' Disease and Hyperthyroidism
A doctor may order a speedtest if you have signs of hyperthyroidism or if you're pregnant with a history of thyroid problems. This test measures the level of thyroid-stimulating immunoglobulin (TSI) in the blood, which can indicate the presence of graves disease, an autoimmune disorder affecting the thyroid gland. Women are more likely to develop this condition than men.
Graves' disease is one of the most common causes of hyperthyroidism, triggered by TSI antibodies. An increased TSI value in the blood typically indicates this disorder, leading to an overproduction of thyroid hormones T3 and T4. Hyperthyroidism can cause symptoms like fatigue, weight loss, and restlessness.
Graves' disease increases the likelihood of developing other autoimmune diseases like type 1 diabetes or Addison's disease. The TSI test can also diagnose other thyroid disorders such as Hashimoto's thyroiditis and toxic multinodular goiter. A doctor may order this test if you have signs of hyperthyroidism or if you're pregnant with a history of thyroid problems.
High levels of TSI in the blood can indicate the presence of graves disease, which can lead to hyperthyroidism. This condition can cause various symptoms and increase the risk of other autoimmune diseases. If you experience signs of hyperthyroidism or have a history of thyroid problems, consult your doctor for a TSI test.
