Description
Thyroid Stimulating Hormone Receptor Antibody (TRAb) testing helps diagnose autoimmune thyroid disorders like Graves’ disease and monitors treatment response; costs ¥200–500 in China, with ChinaMedicalHub assisting hospital booking and interpreter support.
Main Uses
The primary clinical uses of the TRAb test include: 1. Diagnosing Graves' disease, 2. Monitoring the effectiveness of treatment in patients with Graves' disease, 3. Predicting the likelihood of relapse in patients with Graves' disease, 4. Assessing the risk of neonatal hyperthyroidism in pregnant women with a history of Graves' disease, 5. Distinguishing between different types of hyperthyroidism.
Normal Range
The normal range for Thyroid Stimulating Hormone Receptor Antibody (TRAb) is typically less than 1.75 IU/L, but this can vary slightly depending on the laboratory and the specific assay used.
Low Values - Possible Causes
Low levels of TRAb are generally not a concern and do not usually indicate any specific condition. However, in some cases, it may be associated with: 1. Recovery from Graves' disease after treatment, 2. Non-autoimmune thyroid disorders, 3. Normal variation in individuals without thyroid autoimmunity.
High Values - Possible Causes
High levels of TRAb are often indicative of: 1. Graves' disease, 2. Neonatal hyperthyroidism due to maternal Graves' disease, 3. Postpartum thyroiditis, 4. Hashitoxicosis, 5. In some cases, it may also be seen in patients with other autoimmune conditions affecting the thyroid.
