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)
- thyroxine (T4)
- Triiodothyronine (T3)
- Calcitonin- Calcitonin is required for the diagnosis and follow up of medullary thyroid cancer. It is an important tumor marker.
- Carcinoembryonic antigen
- Tests for serum thyroid autoantibodies are sometimes done to rule out autoimmune thyroid disease.
- Laboratory findings consistent with the diagnosis of multiple endocrine neoplasia type 2 are tabulated below.
