Vitamin D is essential for the metabolism and stable equilibrium of calcium and phosphate—elements that are necessary for the growth and development of bones and teeth. Vitamin D also aids in the normal functioning of the body’s nervous system. However, in this era of increased supplementation, there is growing evidence that individuals may be at risk of vitamin D toxicity as a result of overdosing.

To establish the potential impact of mass spectrometry-based Tg quantification on patient care, Mayo Clinic researchers performed a comprehensive analytical and clinical evaluation of immunoassays in thyroid cancer patients. The study, published in the Journal of Clinical Endocrinology and Metabolism, allowed researchers to assess the performance of different serum thyroglobulin assays in the presence of anti-thyroglobulin auto-antibodies.

Serum thyroglobulin concentrations are used to monitor patients with differentiated thyroid cancer, but may be misleading in the presence of antithyroglobulin autoantibodies and heterophile antibodies. Mayo Medical Laboratories has developed an assay to address this issue by testing first for the presence of thyroglobulin antibodies by immunoassay and, in antibody-positive specimens.

Serum thyroglobulin (Tg) measurement is used as a follow-up test for patients with differentiated follicular cell-derived thyroid carcinoma after surgical removal of the thyroid. The Mayo Clinic Endocrine Laboratory has developed an assay that allows accurate quantification of Tg in patients with antithyroglobulin autoantibodies or heterophile antibodies.
