# Thyrotropin Receptor Antibody, Serum

> This test measures the level of thyrotropin receptor antibodies, which are proteins made by the immune system that can interfere with how the thyroid gland functions. It is useful for determining if an overactive thyroid is caused by Graves' disease, an autoimmune condition, rather than other types of thyroid disorders.
