From the expert
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.
FAQs
Does everyone have thyroid antibodies?
No, not everyone has thyroid antibodies. If you do, it may be an indication of having, or being at risk of, an autoimmune disease and we may recommend discussing your results and symptoms with your doctor.
The thyroid antibodies that appear most frequently are:
The thyroid antibodies that appear most frequently are:
- Antithyroglobulin Antibody or TG Ab
- Thyroid Stimulating Immunoglobulin or TSI Ab
- Antithyroid Peroxidase Antibody or TPO Ab (also known as Antithyroid Microsomal Ab)
What does it mean when your thyroid antibodies are high?
Any level (titre) of antibody could be regarded as at least potentially suspicious of future illness. Certain levels of thyroid antibodies may indicate autoimmune disease such as Hashimoto’s disease, Graves’ disease or autoimmune thyroiditis.
When should you check thyroid antibodies?
If a member of your family has a thyroid condition, you have an existing autoimmune disease or you’re experiencing symptoms of an underactive thyroid or overactive thyroid, you may want to check your thyroid antibodies.
It is still possible to have raised levels of all three antibody types and not have any clinical symptoms. This result could indicate that you are at risk of developing a future thyroid condition and you should have follow-up checks to monitor your health.

What are thyroid peroxidase antibodies?
Antithyroid Peroxidase Antibody, or TPO Ab, is often raised in Hashimoto’s disease where the cells for the thyroid gland are attacked and slowly destroyed. Elevated levels are also raised in 65% of patients with Grave’s disease.
