2024年10月2日 · The thyrotropin receptor antibody (TRAb) test is a blood test that helps healthcare providers diagnose the autoimmune thyroid condition called Graves' Disease. The antibodies it tests for are present in between 90% and 100% of the people who have this disease.

2025年2月12日 · High levels of thyroid antibodies appear in your blood when your immune system has attacked cells in your thyroid. Thyroid antibodies include: Thyroid peroxidase antibodies (TPOAb) or anti-microsomal antibodies — the main antibody that signals Hashimoto’s disease; Thyroglobulin antibodies (TgAb)

Thyrotropin-receptor antibody is an autoantibody to the thyroid cell receptor for thyroid-stimulating hormone. It can be demonstrated in 90% of patients with Graves' disease, and is the cause of the hyperthyroidism of that condition.

Thyroid antibodies develop when a person’s immune system mistakenly attacks the thyroid cells and tissues. This leads to inflammation, tissue damage or disrupted thyroid function. These antibodies cause autoimmune thyroid disorders, such …

2017年8月28日 · There are four main types of thyroid antibodies: 1) thyroid peroxidase antibodies, 2) thyroglobulin antibodies, 3) thyroid stimulating immunoglobulins, and 4) thyrotropin-blocking antibodies. Since these antibodies are targeted against the body’s own proteins, they are often referred to as autoantibodies.

These autoantibodies, also known as long-acting-thyroid-stimulators or thyroid-stimulating immunoglobulins (TSI), bind to the receptor and transactivate it, leading to stimulation of the thyroid gland independent of the normal feedback-regulated thyrotropin stimulation.

A thyroid antibody test measures the level of thyroid antibodies in a sample of your blood. Your thyroid is a small, butterfly-shaped gland in your neck. It makes hormones that control many activities in your body, including your heart rate and how fast you burn calories from food.

TRAb (TSH Receptor Binding Antibody) - Measurement of TRAb is used to diagnose and manage Graves' disease, neonatal hypothyroidism, and postpartum thyroid dysfunction. TRAb, which measures the ability of antibodies to inhibit TSH binding to its receptor, reflects the presence of either or both the stimulatory and inhibitory immunoglobulin classes.

Thyroid stimulating hormone receptor (TSHR) autoantibodies (TRAb) play a central role in the evaluation of Graves disease (GD), Graves ophthalmopathy (GO) and pretibial myxedema (PTM). However, there is still controversy regarding overall TRAb assay diagnostic accuracy and their prognostic utility.
