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 possibility of a nodule which secretes thyroid hormone (which is less likely to be cancer) or hypothyroidism is investigated by measuring thyroid stimulating hormone (TSH), and the thyroid hormones thyroxine (T4) and 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 are tabulated below.
| Test | Findings |
|---|---|
| Metabolic | Decreased thyroid stimulating hormone Antithyroid antibodies Elevated calcitonin Decreased calcium |
