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), 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 |
