The TSH Receptor Ab (TRAB) is highly positive, consistent with Graves disease.
Case Discussion
Graves disease is an autoimmune disease characterized by hyperthyroidism triggered by thyroid-stimulating antibodies. Another differential diagnosis for an enlarged thyroid and circulating antibodies includes Hashimoto's thyroiditis. However, the presence of TSH receptor antibody (TRAb) is most consistent with Graves disease.
