Overview
Laboratory findings consistent with the diagnosis of thyroid adenoma include decreased thyroid stimulating hormone, elevated calcitonin, and decreased calcium.
Laboratory Findings
- Blood or imaging tests may be done prior to or in lieu of a biopsy. The following blood tests are conducted:[1]
- Thyroid stimulating hormone (TSH)
- Thyroid hormones thyroxine (T4)
- Triiodothyronine (T3)
- Tests for serum thyroid autoantibodies are sometimes done to rule out autoimmune thyroid disease (which can mimic nodular disease).
- Laboratory findings consistent with the diagnosis of multiple endocrine neoplasia type 2:
- Decreased thyroid stimulating hormone
- Antithyroid antibodies
- Elevated calcitonin
- Decreased calcium
- Antithyroid antibodies
- Serum calcitonin
