The TSH receptor antibody test is performed to check the functioning of the thyroid gland. This blood test detects thyroid antibodies in an individual’s body. The meaning of a positive TSH receptor antibody test is that one is suffering from an autoimmune thyroid disorder such as hyperthyroidism or hypothyroidism. At Max Lab, one can book a well-priced TSH receptor antibody test with an at-home sample collection facility.

Overview of the TSH Receptor Antibody Test

In the human body, the thyroid gland is a butterfly-shaped organ that is responsible for controlling metabolism and a few other bodily functions. This gland produces two hormones, triiodothyronine and thyroxine, called T3 and T4, respectively. TSH, or thyroid stimulating hormone, is something that regulates the production of T3 and T4. There are certain medical conditions that affect the production of these hormones, leading to thyroid-related issues such as hyperthyroidism and hypothyroidism.

The TSH receptor antibody test, commonly known as the TRAb test, helps with the diagnosis of these conditions by detecting thyroid antibodies. If the result of the TSH receptor antibody test is not within the normal range, it indicates the presence of either of the two. When the result value of TSH receptor AB is high, it indicates hypothyroidism. On the other hand, a low result value for the TSH receptor antibody test indicates hyperthyroidism.

A negative result for the TSH receptor antibody test means that the thyroid symptoms one is experiencing are not caused by an autoimmune disease. In such cases, additional tests are required for a diagnosis.
