Thyroid
Also known as: Thyroid autoantibodies, TSH receptor antibody, TRAb
If you experience sudden severe symptoms like rapid heart rate, chest pain, shortness of breath, or sudden weakness, seek immediate medical attention. These could be signs of a thyroid storm, a rare but serious complication of hyperthyroidism.
This test checks for something called TSI in your blood. TSI is a special kind of antibody. These antibodies can make your thyroid gland work too much.
Your doctor may order this test if you have signs of a thyroid that is too active. This is called hyperthyroidism. They might think you have Graves' disease. This is a sickness where your body's defense system attacks your thyroid. The test can also be used if you are pregnant and have had thyroid problems before.
Reference ranges for TSI can vary between different laboratories. Your healthcare provider will interpret your results based on the specific ranges used by the lab that performed your test.
