Overview

Dr. Spencer’s major areas of research interest are thyroid physiology and pathology, thyroglobulin and thyroid cancer, immunoassay techniques, thyroid hormone metabolism, and the cost-effective use of thyroid tests. Her current research includes clinical significance of Tg and TgAb in patients with thyroid cancers, parameters for optimizing thyroid hormone suppression of TSH for DTC. Studies on hypothalamic/pituitary mechanisms for regulating TSH, and testing for thyroid dysfunction during pregnancy.

Dr. Spencer earned her PhD from Glasgow University in Scotland. She then went on to complete two fellowships, one in Clinical Biochemistry at Glasgow, and the other at the National Academy of Clinical Biochemistry.
