Our Advanced Thyroid Function Blood Test contains everything you need to give you a clear picture of your thyroid health. This profile includes tests for thyroid stimulating hormone (TSH), thyroid hormones (FT4 and FT3) and thyroid antibodies (thyroglobulin antibodies and thyroid peroxidase antibodies) for a thorough investigation of thyroid function and autoimmune disorders which could be causing your symptoms. Importantly, it also tests for free triiodothyronine (FT3) and the more

biologically active free thyroxine (FT4), which could help to explain any symptoms you may have.

​

This profile includes important vitamins and minerals which not only support your thyroid function, but which can also mimic the symptoms of an underactive thyroid if they are found to be low. We include tests for vitamin D, vitamin B12 and folate (vitamin B9) and ferritin (a marker for iron storage). We also include an inflammation marker to help interpret your iron (ferritin) result as well as give a picture of whether an autoimmune condition is causing inflammation in your body.
