What is a Thyroid Function with Antibodies Blood Test?
Our Thyroid Function with Antibodies Blood Test offers an affordable insight into what could be causing your thyroid-related symptoms - and many people begin their investigation into a thyroid condition with this test. This test includes thyroid-stimulating hormone (TSH), free thyroxine (FT4), and free triiodothyronine (FT3). By measuring the amount of thyroid hormone that is free or unbound to carrier proteins in the blood, you can get a better picture of how much thyroid hormone is available to your cells. Additionally, this test also includes tests for thyroglobulin and thyroid peroxidase antibodies.
What causes a thyroid condition?
Many thyroid-related conditions are caused by autoimmune diseases. Your risk for this is raised if you or a family member has a history of autoimmune disease. Our test looks for specific thyroid antibodies, which can indicate that your thyroid is under attack by your immune system.
What autoimmune diseases affect the thyroid?
The two main autoimmune conditions that affect the thyroid are Hashimoto's thyroiditis (which causes hypothyroidism) and Graves' disease (which causes hyperthyroidism). While there isn’t a cure for either of these, they can be managed with the right treatment plan – so getting tested is important. Your doctor will take your symptoms into account alongside doing some thyroid blood tests to give you a diagnosis of a thyroid disorder.
