Thyroid Nodules (cont.)
Thyroid Blood tests
- Thyroid stimulating hormone (TSH) levels and levels of thyroid hormone can indicate whether the thyroid is underproducing or overproducing thyroid hormones.
- Anti-thyroid antibody levels can indicate the presence of autoimmune thyroid inflammation that can be seen with Hashimoto's thyroiditis (underactive thyroid disease called hypothyroidism) or Graves' disease (overactive thyroid disease called hyperthyroidsim).
- Calcitonin levels in the blood can suggest a specific type of thyroid cancer, known as medullary carcinoma of the thyroid. However, calcitonin testing is generally not recommended as part of an initial evaluation of a thyroid nodule.
