A Novel Bioreporter Assay for Thyrotropin Receptor Antibodies Using a Chimeric Thyrotropin Receptor (Mc4) Is More Useful in Differentiation of Graves' Disease from Painless Thyroiditis Than Conventional Thyrotropin-Stimulating Antibody Assay Using Porcine Thyroid Cells

Abstract

These data suggest that the Thyretain bioreporter assay with a chimeric TSHR (Mc4) is more useful in the differential diagnosis of GD from PT than the bioassay with wild-type TSHR on porcine thyroid cells.
