About Tsh receptor stimulating antibodies

What are thyroid-stimulating hormone (TSH) receptor stimulating antibodies?

Thyroid-stimulating hormone (TSH) is a hormone produced by the pituitary gland. Its primary role is to stimulate the thyroid to secrete thyroxine (T4) and triiodothyronine (T3), which regulate metabolism throughout the body.

TSH acts on receptors in the thyroid gland called TSH receptors. Anti-TSH receptor antibodies (TRAb) are autoantibodies produced by the immune system which target these receptors, causing either stimulation or blockage of the receptors.

The presence of TRAbs is associated with Graves’ disease and hyperthyroid patients.

Why take the test?

This test screens for anti-thyroid-stimulating hormone receptor stimulating antibodies in the blood. It is typically used to diagnose thyroid autoimmune conditions such as Graves’ disease.
