Overview
Laboratory findings consistent with the diagnosis of medullary thyroid cancer 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:
- Thyroid stimulating hormone (TSH)
- Thyroid hormones thyroxine (T4)
- Triiodothyronine (T3)
- Calcitonin
- Carcinoembryonic antigen
- 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 |
