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:
  • 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: [1]
