TSI Bioassays More Sensitive Than Binding TSH-R-Abs Assays Among Patients With AITD, Study Suggests

Endocrinology Advisor (8/14, Nye) reports, “Thyroid-stimulating [immunoglobulin] (TSI) bioassays are more sensitive than binding thyrotropin receptor antibodies (TSH-R-Abs) assays among patients with autoimmune thyroid disease (AITD), according to results of a study.” The researchers concluded that “TSH-R-Ab is an important biomarker in the evaluation and management of patients with AITD in general and [Graves disease] in particular.” The findings were published in the Journal of Clinical Endocrinology & Metabolism.
