Test Overview
Competitive assay with electrochemiluminescence detection
Measurement of Thyrotropin Receptor Antibody (TRAb) is used to diagnose and manage autoimmune thyroid disease (i.e., Graves disease), neonatal hypothyroidism, and postpartum thyroid dysfunction. The test is the recommended first-line test for detection of thyrotropin receptor antibodies and measures the presence of stimulating, blocking and neutral antibodies. Using a decision limit of 1.75 IU/L, the test has a sensitivity of 97% and a specificity of 99% for detection of Graves disease.
0.00 - 1.75 IU/L
