Formerly known as Thyroid Check Plus Blood Test

Many people begin their investigation into a potential thyroid condition with our Thyroid Function with Antibodies Blood Test. It offers a comprehensive investigation into the main thyroid hormones (TSH, FT4 and FT3) as well as thyroglobulin antibodies and thyroid peroxidase antibodies.

Thyroid conditions are very common but can be difficult to diagnose - many of the symptoms of a thyroid disorder can be overlooked (especially if they are mild) or confused with other conditions. This test offers an affordable insight into what could be causing your symptoms by checking your levels of thyroid stimulating hormone (TSH), which is often abnormal in thyroid disease, 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, we can get a better picture of how much thyroid hormone is available to your cells. 

Many thyroid disorders are caused by an autoimmune disease and your risk for this is raised if you or a family member has a history of autoimmune disease. This test looks for specific thyroid antibodies which can indicate that your thyroid is under attack from your immune system.

Dr Sam Rodgers MBBS, MRCGP
