Whether the antibodies cause the disease or whether the disease causes the antibodies is not known; however, the finding of a high level of thyroid antibodies is strong evidence of this disease. Sometimes the diseased thyroid gland will start producing very high levels of T3 but still produce normal levels of T4. A thyroid scan can help to determine if a thyroid nodule is "hot," meaning it produces too much thyroid hormone, or "cold," meaning it does not. Medication, radioiodine therapy, and surgery are … During this test, an isotope of radioactive iodine is injected into a vein in your arm.
